The stub executables in the repository need to be updated, although the old ones should work fine (some of them are currently out of sync w.r.t. the source code).

This looks like an installation of wx that's not in sync with Python. In particular, the python interpreter supports a different CPU architecture than wxPython.

The quickest solution based on the list of packages you installed is to download the 32-bit installer for Python (not the intel-only installer for OSX 10.6 or later).
