The usual way of doing this is

import numpy
...
setup(
    ...
    ext_modules = [Extension(..., include_path=[numpy.get_include()])]
)

No need to alter include paths etc. then.

(It would be great if somebody could take the time to add this question 
to the FAQ and/or the Cython/NumPy tutorial, it comes up a lot.)
