[pygtk] Installing pygtk

[Reik H. Börger]

Hello,

I am new to this list, the world of unix and python. I need to use the 
matplotlib library in python and I decided to use a backend, which 
requires pygtk. So I downloaded it (2.4.1), built it (after collecting 
all the necessary other parts) and when I start python and type
import pygtk
everything seems fine.

But when I type
import matplotlib.matlab

I get the following message:
No module named pygtk
PyGTK version 1.99.16 or greater is required to run the GTK Matplotlib 
backends

What happened?
Thanks for your help
