No module named gobject

[Alex Ivanov <alex 3dplumbing net>]

Hi. I installed garnome-2.20.2, and it is very cool. The problem is
that pygtk seems to be broken, because GIMP doesn't work properly. It
has no plugins in the Scrip-Fu menus. When I launch GIMP in the
terminal, I get these errors:

------------------------------------------

When I try to launch pygtk-demo, I get this error:
$ /home/rex/garnome/bin/pygtk-demo 
Traceback (most recent call last):
  File "/home/rex/garnome/bin/pygtk-demo", line 7, in ?
    execfile(os.path.join(pygtklibdir, "pygtk-demo.py"))
  File "/home/rex/garnome/lib/pygtk/2.0/pygtk-demo.py", line 18, in ?
    import gobject
ImportError: No module named gobject
-------------------------------------------

But I am pretty sure that gobject exists:
find /home/rex/garnome -name gobject
/home/rex/garnome/share/gtk-doc/html/gobject
find: /home/rex/garnome/var/lib/hal: Permission denied
/home/rex/garnome/lib/python2.4/site-packages/gtk-2.0/gobject
/home/rex/garnome/include/glib-2.0/gobject
-------------------------------------------

Does anybody know how to fix? I am on Debian Etch.
Thanks. Alex.
