Mysql 5.0 and Django Subversion 6917.
I switched from sqlite3 to mysql 5.0 midway through development, First, I edited settings.py to reflect the database changes. Next, I had to run
$ python manage.py reset auth --noinput
first, in order setup a new admin user by executing
$ python manage.py flush
Finally, I made all the tables in settings.py by running
$ python manage.py syncdb
