The error is not in matplotlib, it is in a pygtk header file, which is 
presumably coming from a Redhat package.  I don't know why it is 
happening or what the best solution is, though.  It looks like the 
pygobject.h that I have has "typename_", not "typename", so I am 
thinking maybe this is a pygtk bug, since fixed, in which "typename" is 
in conflict with something.  You might try editing your copy of 
pygobject.h, adding the trailing underscore to "typename" on both lines 
where it occurs.  It can't hurt; these are just dummy variable names.
