Hi HA,
I am a little confused by this, but at least your PYTHONPATH variable seems to be set to a fink tree, rather than a homebrew one.
It should probably be: /usr/local/lib/python2.7/site-packages
rather than: /sw/bin/local/lib/python2.7/site-packages
However, this will probably not matter, since the PyQt4 error is indeed coming from /usr/local.
We will try to get a homebrew machine set up and see what we find.
