python setup.py install works well, and has for almost a decade.

If you need setuptools, you can include ez_setup.py, which does
exactly what you want, without adding a hugely controversial feature
to python proper. You do something like:

     import setuptools
except ImportError:
     print "Run ez_setup.py first"

And you're done,
