actually I originally switched to arch to have pygtk available for the python
version in use. but this is just marginally related to your issue, which is IMO
sufficiently invalidated by [1].

#!/usr/bin/env python2 and #!python2 in my experience have exactly the same
effect, so all I can do is ask you what differences you found and then we could
discuss how to work them around.

A good proof of concept / educating experiment in that context would be to try
running a python and pygtk fully in your home directory and without the repo
versions present; if you have questions, please come back here with more
factual questions. I'll gladly help you out.

cheers!
