ImportError: No module named modelsinspector

Why have you installed South 0.5? The current version of South is 0.7.3 - 0.5 is more than two years old and dates from before the reorganisation that added the modelsinspector module. Delete that version and install the latest one.

You are missing module modelsinspector. Install it.
