import pymongo works in Python interpreter but not script

Question

I first installed pymongo using easy_install, that didn't work so I tried with pip and it is still failing.

This is fine in the terminal:

Macintosh:etc me$ python
Python 2.7.2 (v2.7.2:8527427914a2, Jun 11 2011, 14:13:39) 
[GCC 4.0.1 (Apple Inc. build 5493)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import pymongo
>>>

But on line 10 of my script

import pymongo

throws the following error:

File "test.py", line 10, >in <module> import pymongo ImportError: No module named pymongo

I'm using the standard Lion builds of Apache and Python. Is there anybody else who has experienced this?

Thanks

EDIT: I should also mention that during install it throws the following error

Above is the ouput showing how the compilation failed.

And then goes on to say

Successfully installed pymongo

Macintosh:etc me$

Very odd.

My sys.path in script is returned as:

Maybe your python path differs in interpretator and in a script? What's your sys.path in both cases? — Michał Zieliński
Hi Michal, I have edited my post with both outputs. Thanks for yourt time :) — Dom Vinyard

Found it! Required a path append before importing of the pymongo module

sys.path.append('/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages')
import pymongo

Would ideally like to find a way to append this to the pythonpath permanently, but this works for now!
