[gpm] docbook2man issue

[Lupine <thelupine gmail com>]

gnome-power-manager-2.18.3 fails to make on my BLFS box.  It's weird,
because I'm just having a problem with docbook2man:

make[2]: Entering directory `...gnome-power-manager-2.18.3/man'
docbook2man gnome-power-preferences.sgml > gnome-power-preferences.1
I/O error : Attempt to load network entity
http://docbook2x.sf.net/latest/xslt/man/docbook.xsl
warning: failed to load external entity

make[2]: *** [gnome-power-preferences.1] Error 2

I checked my version of docbook2man, and updated to latest 0.8.8 version
from:
http://docbook2x.sourceforge.net/
http://downloads.sourceforge.net/docbook2x/docbook2X-0.8.8.tar.gz
I've also Googled around, and installed every Perl::XML updated I could
find. Nothing seems to help.

I don't really care about the man pages all that much, so I decided to
try and bypass this error by configuring GPM like this:
./configure --prefix=/opt/gnome --sysconfdir=/opt/gnome/etc
--libexecdir=/opt/gnome/lib/gnome-power-manager --localstatedir
=/var/lib --disable-docbook-docs
....however, I guess I can't trick it with "--disable-docbook-docs"
because I still get the above error.

I'm running out of things to try, so I've turned to the list for help.
Any suggestions?
