Django is attempting to issue the following command (or some variant of it):
import collections
And is failing. This could be because your installation is missing components . You can verify it's not a django related issue by doing the following:
Pythoness-410:auth gfleche$ python
>>> import collections
If you get an error back, then it's likely to be an issue with your python installation - since collections has been around for some time, and is part of the standard install.
