Hi!

[snip - distutils should leave #!/usr/bin/env python alone] Comments? (I first posted this to distutils-sig but was told that distutils is a bit neglected there, so I decided to try to push these simple patches in via python-dev.) How about a distutils installation command line option to tell it to use this behavior? People with unusual environments can select it.

This would be best I think. There's a related problem here. Many
operating systems (e.g. various Linux distros) provide system scripts
written in Python and they incorrectly use /usr/bin/env. The problem
is that if you have your own version of Python earlier in your $PATH,
you can break these scripts. This happens when say your /usr/local/ bin/python doesn't have the packages that your /usr/bin/python
expects. I've hit this quite a few times on Gentoo for example. In
these cases, you really do want the #! line to point to the OS's
version of Python rather than whatever random installation is on your
$PATH.
