Many operating systems and distributions now use Python extensively.   
Those should absolutely hardcode the #! line to use the system Python  
and should not in any way be affected by my $PATH.  I've seen too many  
situations where changing $PATH breaks some aspect of the OS.

I happen to think that setuptools is doing the right thing here, but  
it would be nice to have an override.
