Generally, *if* you have multiple versions installed and want to know
which version is actually imported, cd to postorius/dev_setup, open up a
Python shell and try the following:

 >>> import django
 >>> django.__file__  # prints the package path
 >>> django.VERSION   # prints the django version

Django tries to find a 500.html file to display a standard error page.
It cannot find one and raises TemplateDoesNotExist. But the more
important question is: What's the actual cause for the 500 internal
server error?

IIRC Django only looks for a 500.html in non-DEBUG mode, so my guess is
that your DEBUG setting in dev_setup/settings.py is set to False. If
that is the case a good next step would be to set it to True and have a
look at the traceback again - it should be much more detailed than the
one you're seeing right now and (hopefully) give us a clue what's
actullay going wrong.

If you like paste the traceback to some of the various pasters out there
(like paste.ubuntu.com) and post the link to it here - it's much easier
to read then.
