Garnome 2.22.0: ffi missing as a dependency of pygtk, as a dependency of alacarte

["Michael Schmarck" <michael schmarck habmalnefrage de>]

Hello.

I'm doing a "make paranoid-install" (in the *desktop* directory *g*) and
it fails to build alacarte. In config.log, there's:

configure:6469: $? = 0
configure:6545: result: yes
configure:6550: checking for pygtk 2.8.0 installed for python 2.4
Traceback (most recent call last):
  File "<string>", line 3, in <module>
  File "/data/Gnome2.22/garnome/lib/python2.5/site-packages/gtk-2.0/gobject/__init__.py",
line 30, in <module>
    from gobject.constants import *
  File "/data/Gnome2.22/garnome/lib/python2.5/site-packages/gtk-2.0/gobject/constants.py",

    from _gobject import type_from_name
ImportError: libffi.so.4: cannot open shared object file: No such file
or directory
configure:6561: result: not found
configure:6563: error: required pygtk version not found

libffi isn't shipped with Garnome 2.22.0, is it? I'm using Gentoo
Linux ~x86 and don't have the libffi package installed. Should
libffi be a dependency that's supposed to be shipped by the
Linux distribution?
