Which version of pygtk are you running?  With reasonably recent pygtk (from 
fecora 3) and matplotlib, I don't see any of this:

In [1]: matplotlib.__version__
Out[1]: '0.83.2'

In [2]: import pygtk

In [3]: pygtk._get_available_versions()
Out[3]: {'2.0': '/usr/lib/python2.3/site-packages/gtk-2.0'}


I remember there used to be a require() call before, but at some point in the 
last 6 months it was removed, I believe in order to follow the conventions of 
more current pygtk.  I may have been wrong in that though, I know precious 
little about the GTK API (as evidenced by the thread with C. Moad an S. Moore 
on ipython-user).

Cheers,
