I'm using:

• python version 2.7.2
• numpy version 1.6.2
• setuptools version 18.4
• cython version 0.24.1

I modified |setup.py| with the attached patch

and it worked. I'm not familiar with python setup so can't comment on
why this is necessary but wanted to flag it in case it's useful to
anyone else.
