numpy.distutils uses setuptools if it is importable in order to make sure that the two don't stomp on each other. It's probable that that test could probably be done with Andrew Straw's method:

if 'setuptools' in sys.modules: havesetuptools = True from setuptools import setup as oldsetup else: havesetuptools = False from distutils.core import setup as oldsetup Tested patches welcome.

Well, tested as in 'I wrote a unittest for installation', no. But tested as in 'I built numpy, scipy, matplotlib, and my f2py-using code', yes. They all build/install fine, and no more *egg-info directories are strewn around.

If this satisfies your 'tested patches', the code is:

May I?
