Summary: install_lib fails under Python 2.1

Initial Comment:
distutils/command/install_lib.py references os.extsep.
os.extsep is only available in pythons >= 2.2
(The result, naturally, is an uncaught AttributeError.)

Here's a quick patch (though the patch is flawed if
os.extsep is ever anything but '.' --- is it?)

Closing it as fixed. A backport to 2.3 would be pointless,
since 2.3 does have extsep. This change only matters
assuming there will be a separate distutils release some
day, which is doubtful.

This has been fixed in CVS HEAD, and can be closed. It is
probably  a backport candidate to Python 2.4 (I can't check
if that has been done). It's likely too late for 2.3...

A somewhat simpler version:

  PYTHON_SOURCE_EXTENSION = getattr(os, 'extsep', '.') + "py"
