3to2 as I understand it works best for supporting Python 2.6 and 2.7 Django had committed to supporting older versions of Python 2.x that weren't Python 3 friendly (largely because of older installations of RHEL and CentOS). Here was a discussion asking about dropping 2.4 support during development of Django 1.3: http://python.6.n6.nabble.com/Django-1-3-and-Python-2-4-td509988.html http://python.6.n6.nabble.com/Django-1-3-and-Python-2-4-td50... Django 1.2 still supported Python 2.3+, Django 1.3 supported Python 2.4+, Django 1.4 supported Python 2.5+. Django 1.5 (which is the current trunk) finally has Python 2.6.5 as its minimum platform which reduces some of the major compatibility pain points.
