The include directory is not in the list of directories to search for 
the header files and so it is not being found.  I'm not sure what would 
cause this.  It's possible that the windows system doesn't have NumPy 
installed (or else the headers are not installed).  Or, it's possible 
that numpy.distutils is not adding the NumPy directory to the list of 
directories to search for header files.

I'm not sure why it's not adding the location of the NumPy headers to 
the compile line.
