Error importing pymongo in my django app

Question

I'm trying to insert documents into mongodb from django and I'm getting an error on the import statement for pymongo. I don't have a duplicate file anywhere called pymongo and I'm pretty sure my virtualenv is set up correctly.

(django-sample-app)ubuntu@django (884) ~ $ python

Python 2.7.3 (default, Aug  1 2012, 05:14:39)

>>> import bson

>>> import pymongo

This error happened to me after pip install (in virtualenv) both pymongo and bson.

Uninstall pymongo and bson and install again just pymongo - it ships with its own version of bson not compatible with the bson package.
