Weird. When I do 'show original' for /usr/bin/python, it shows as a  
symlink to

/System/Library/Frameworks/Python.framework/Versions/2.5/bin/python

...which is a symlink to /System/Library/Frameworks/Python.framework/ 
Versions/2.5/bin/python2.5

BUT, if I start it...

cmb-MBP-2:~ cmbarton$ python

So it IS the shebang at the top.

So what to do to make this work?

#!/usr/bin/env python ????

This works on my Mac. Does it work for others?
