I am preparing fixes to Satchmo for Django 1.4
= South = Due to dependency on South, clonesatchmo.py currently writes warnings "RuntimeWarning: DateTimeField received a naive datetime (2012-03-...) while time zone support is active." With the stable South 0.7.3.
The South issue http://south.aeracode.org/ticket/1012 related also to time zones is the blocking issue why South 0.7.4 can not be released yet.
I temporarely change the installation source from stable to development until 0.7.4 is released. (it solves our problem)
