Not sure what you mean, since numpexpr already uses setuptools:
https://github.com/pydata/numexpr/blob/master/setup.py#L22. What is the
real goal you're trying to achieve?

This monkeypatching is a bad idea:
https://github.com/robbmcleod/numexpr/blob/numexpr-3.0/setup.py#L19. Both
setuptools and numpy.distutils already do that, and that's already one too
many. So you definitely don't want to add a third place.... You can use the
-j (--parallel) flag to numpy.distutils instead, see
http://docs.scipy.org/doc/numpy-dev/user/building.html#parallel-builds
