Apache Configuration Question

Syntax Error with Django, WSGI, and Apache

I am getting a weird error while trying to run my Django site under Apache using mod_wsgi. I have been working on this for hours to no avail.

FYI: I am also using Mezzanine.

Log:

Python 2.6 doesn't support set syntax {....}

You may use a version of Django that supports Python 2.6 but make sure it also supports Mezzanine OR Update your Python installation to 2.7
