I managed to fix the same error by using these packages on github:
https://github.com/django-nonrel/django-nonrel
https://github.com/django-nonrel/djangotoolbox
instead of the ones recommended on Django-Mongodb's setup page. Also, make sure to use the master branch of each, so as to not run into compatibility problems. If you're using pip, you can either pip install each of the following lines separately, or put them into your version of a requirements.txt file for your project:
git+https://github.com/django-nonrel/django-nonrel#master
git+https://github.com/django-nonrel/djangotoolbox#master
git+https://github.com/django-nonrel/mongodb-engine#master
And then run
pip install -r requirements.txt
