[python-uk] embedding python ImportError: libpyglib PyExc_ImportError

Well, do you have that library on your system?  The problem is that you are
loading a Python module that uses a C extension module under the hood so
your python runtime is looking to load in that library as you import that
module but its not finding it.

How have you "installed" the gtk module so your embedded Python can see it?
 I've never embedded Python in a C application before but I'll do what I can
to help you :)

BTW: A great site for quick answers to questions like this (if you don't
already know it) is stackoverflow.com
