I installed ubuntu 12.04 64-bit I have python 2.7 with some additional packages. When I try to use simple command in python like for example help('modules')
I have an error and python terminates.
>>> help('modules')
Please wait a moment while I gather a list of all available modules...

In addition I cannot install matplotlib. In a long error log, apart of other stuff I have:
pkg-config: looking for pygtk-2.0 gtk+-2.0

* search path. Perhaps you should add the directory

I tried to install gtk from synaptic but did not find exact match for gtk and installed libraries with its dependencies which I thought are the closest. I am not sure how to test if I have it correctly installed and how to fix my python's problem
