This line in my .bashrc solves the same problem on my Mac

export C_INCLUDE_PATH=/Library/Python/2.5/site-packages/numpy/core/include

Or, I think you could add the same path to your definition of the
Extension() in setup.py. I think you can do this:

ext_modules = [Extension("neuralRoutines", ["neuralRoutines.pyx"],
        extra_compile_args=['-Ithe/path/you/want/here'],
)]

... but I haven't checked it.

It looks like you've got a few versions installed. You'd best figure out
which one you are actually using, and delete the rest...
