[yt-users] Installation script issue with pygtk

A followup:

I tried the install script on a different machine and it installed fine.  I
then went back to my original machine and mv'ed the
~/.matplotlib/matplotlibrc file out of the way and the ipython session
started properly with iyt.

So something in my matplibrc file is causing the crash, but the only warning
I received was that the numerix param was obsolete.  I tried just commenting
out that particular line in the matplotlibrc file but I still recieve the
same errors as before.  Any ideas what else in the matplotlibrc file could
be causing the crash?
