You need a glibc or a kernel patch. Basically, the problem is that the
poll() syscall it tries returns EPERM, not ENOSYS, so glibc never reverts
to the select() emulation. I'll attach my glibc patch below. The kernel patch
is also simple, in arch/alpha/kernel/traps.c::do_entSys(), change the
"return -1" to "return -ENOSYS".

I'm running the glibc kludge, and its working fine. I've been assured by
Richard Henderson that the kernel patch wont break anything.

%description
Contains the standard libraries that are used by multiple programs on
the system. In order to save disk space and memory, as well as to
ease upgrades, common system code is kept in one place and shared between
programs. This package contains the most important sets of shared libraries,
the standard C library and the standard math library. Without these, a
Linux system will not function. It also contains national language (locale)
support and timezone databases.

Summary: glibc with debugging information
Group: Development/Libraries/Libc
Summary(de): glibc mit Debugging-Info
Summary(fr): glibc contenant des informations pour le débuggage
Summary(tr): Hata ayıklama bilgileriyle oluşturulmuş glibc

%description debug
These libraries have the debugging information debuggers use for tracing
the execution of programs. These are only needed when the shared libraries
themselves are being debugged -- they are not needed to debug programs which
use them.

%package devel

Conflicts: texinfo < 3.11
Prereq: /sbin/install-info

Summary(tr): Geliştirme için gerekli diğer kitaplıklar

%description devel
To develop programs which use the standard C libraries (which nearly all
programs do), the system needs to have these standard header files and object
files available for creating the executables.

%package profile
Summary: glibc with profiling support
Group: Development/Libraries/Libc

Summary(tr): Ölçüm desteği olan glibc

%description profile
When programs are being profiled used gprof, they must use these libraries
instrad of the standard C libraries for gprof to be able to profile
them correctly.

%description -l de debug
Diese Libraries enthalten die Debugging-Daten, die Debuggers zum Verfolgen
der Ausführung von Programmen verwenden. Sie benötigen diese nur, wenn
die gemeinsam genutzten Libraries debugged werden - sie werden zum Debuggen
von Programmen, die sie benutzen, nicht benötigt.

%description -l de profile
Damit Programmprofile mit gprof richtig erstellt werden, müssen diese
Libraries anstelle der üblichen C-Libraries verwendet werden.

%description -l de devel
Bei der Entwicklung von Programmen, die die Standard-C-Libraries verwenden
(also fast alle), benötigt das System diese Standard-Header- und Objektdateien
zum Erstellen der ausführbaren Programme.

%description -l de
Enthält die Standard-Libraries, die von verschiedenen Programmen im 
System benutzt werden. Um Festplatten- und Arbeitsspeicher zu sparen 
und zur Vereinfachung von Upgrades ist der gemeinsame Systemcode an 
einer einzigen Stelle gespeichert und wird von den Programmen 
gemeinsam genutzt. Dieses Paket enthält die wichtigsten Sets der 
shared Libraries, die Standard-C-Library und die Standard-Math-Library, 
ohne die das Linux-System nicht funktioniert. Ferner enthält es den Support 
für die verschiedenen Sprachgregionen (locale) und die Zeitzonen-Datenbank.

%description -l fr debug
Ces bibliothèques disposent d'information de débuggage pour tracer l'exécution
des programmes. Elles ne sont nécessaires que lorsque les bibliothèques
partagées ont été elles-mêmes débuggées -- elles ne sont pas nécessaires pour
débugger les programmes qui les utilisent.

%description -l fr devel
Pour développer des programmes utilisant les bibliothèques standard du C
(ce que presque tous les programmes font), le système doit posséder ces
fichiers en-têtes et objets standards pour créer les exécutables.

%description -l fr
Contient les bibliothèques standards utilisées par de nombreux programmes
du système. Afin d'économiser l'espace disque et mémoire, et de faciliter
les mises à jour, le code commun au système est mis à un endroit et partagé
entre les programmes. Ce paquetage contient les bibliothèques partagées les
plus importantes, la bibliothèque standard du C et la bibliothèque
mathématique standard. Sans celles-ci, un système Linux ne peut fonctionner.
Il contient aussi la gestion des langues nationales (locales) et les bases
de données des zones horaires.

%description -l tr debug
Programların çalışmalarını izlemek (trace) ve hata ayıklamak için kullanılan
kitaplıklar. Bunlar sadece ortak kitaplıkların hatalarını ayıklamak
isteyenlere gerekecektir.

%description -l tr profile
gprof kullanılarak ölçülen programlar standart C kitaplığı yerine bu
kitaplığı kullanmak zorundadırlar.

%description -l tr devel
C kitaplığını kullanan (ki hemen hemen hepsi kullanıyor) programlar
geliştirmek için gereken standart başlık dosyaları ve statik kitaplıklar.

%description -l tr
Bu paket, birçok programın kullandığı standart kitaplıkları içerir. Disk
alanı ve bellek kullanımını azaltmak ve aynı zamanda güncelleme işlemlerini
kolaylaştırmak için ortak sistem kodları tek bir yerde tutulup programlar
arasında paylaştırılır. Bu paket en önemli ortak kitaplıkları, standart
C kitaplığını ve standart matematik kitaplığını içerir. Bu kitaplıklar olmadan
Linux sistemi çalışmayacaktır. Yerel dil desteği ve zaman dilimi veri tabanı
da bu pakette yer alır.

- figured out how to handle newer kernels on alpha - back to 2.1.76
- added a patch to address case-sensitve hosts and aliases lookup brokeness
- re-added the patch for alpha/net/route.h, which somehow escaped the
  official release
- added the threads and thread-signal patches from Andreas Jaeger

* Mon Dec 29 1997 Cristian Gafton <gafton@redhat.com>
- finally 2.0.6 final release is here...
- reverted to kernel headers 2.1.60. Although the latest one available
  should be used (2.1.76 at the moment), the new kernel headers break
  compilation on alpha (due to the rename of the __NR_sigaction to
  __NR_old_osf_sigaction). In two days I haven't figured out the correct
  place to modify this on glibc sources, so...
