That's probably a bug in numpy.distutils, and probably the part that I wrote for
OS X support. I'll look into it. Note that you can add link flags like this
directly to build_ext:

python setup.py build_ext --library-dirs=/usr/local/lib:/some/other/lib build

Hopefully, that's not going to interfere with any other settings.
