embedding python ImportError: libpyglib PyExc_ImportError linking

Question

I am running 64 bit ubuntu 10.10 in case there are know issues with this setup, basically i am embedding python inside a c application i managed to get this to work i can call functions from the original c program and the scripts run until i import gtk in the python script this causes the error below.

I am using the waf build system to build the c program, my knowledge of c is limited i am more a python programmer which is why i am attempting the embed python so i can write my plugins in python.

I get the feeling the error is todo with linking but i dont get why i can import gtk normally in python but not when its embeded ?

I can confirm the lib its looking for exists with the commands below. locate /usr/lib/libpyglib /usr/lib/libpyglib-2.0-python2.6.so.0 /usr/lib/libpyglib-2.0-python2.6.so.0.0.0

Any help or pointers would be appreciated, that might help me get this solved or better understand what is wrong.

Traceback (most recent call last):

PyExc_ImportError
Failed to load the "gpykickstart" module from the
"/usr/local/share/geany/plugins" directory.

This is the code i am trying to run in the embeded python interpreter, if i take out the import gtk option it works fine.

import sys
import pygtk
pygtk.require('2.0')
import gtk

Here is the c code i currently have i have tried to strip it down to a minimum to just load the python file and reproduce the error.

If you want the wscript that i am using i can post this as well.
