[Matplotlib-users] ImportError: No module named _backend_gdk

[Sebastian P. <spc...@gm...>]

Hello
I don't know why, but after switching from python2.5 to python2.6 I
cannot even launch matplotlib (matplotlib-0.98.5.3.win32-py2.6.exe).
This is what I get:

Traceback (most recent call last):

ImportError: No module named _backend_gdk


I have PyGTK installed. What can be the problem?
