python2 import trouble (linux - redhat)

[Mike Mellor]

Hello - 

I am using RH7.2, and have the following python packages 
installed:

python-devel-1.5.2-35
rpm-python-4.0.3-1.03
pygtk-0.6.8-3
python2-docs-2.2.1-1
pygnome-libglade-1.4.1-3
python-xmlrpc-1.5.0-1
pygtk2-1.99.8-2
pygtk-glarea-0.6.8-3
python2-devel-2.2.1-1
PyXML-0.6.5-4
pygtk-devel-0.6.8-3
python2-2.2.1-1
pygtk2-libglade-1.99.8-2
python-1.5.2-35
pygtk-libglade-0.6.8-3
python2-tkinter-2.2.1-1
pygnome-1.4.1-3
python2-tools-2.2.1-1

I am having trouble importing modules with python2 (Python 2.2) that I think should be 
there, for example, _gtk and GTK.  What do I need to do to get 
python (actually python2) to import these modules?

Thanks.

Mike
