The major thing to realise here is that setup.py, being a Python program,
will normally set your programs up to use the same version of Python that
you used to run the setup itself. This is useful when (as discussed in
another thread recently) one has multiple copies of Python on a single
machine.

I like to test that new modules will install on Windows and Cygwin on my
laptop, even bfore I get them down into the basement for stress-testing :-)

I wouldn't worry too much as long as everything works: if you really have a
/usr/bin/python then it's quicker than using /bin/env python.
