GTk backend problem

I recently upgraded to Enthought python 2.6 an so I have now matplotlib 0.99.3
My scripts now no longer seem to find the pyGTK since when I run them I got this message:

Traceback (most recent call last):
   File "./", line 14, in <module>

     raise ImportError("Gtk* backend requires pygtk to be installed.")
ImportError: Gtk* backend requires pygtk to be installed.

is any way to help matplotlib to point the where pyGTK is or go around the problem with another backend?
