You don't say what type of build system it is. If it's autoconf or  
Makefile based, you could do something like

NUMPY_HEADERS=$(python -c 'import numpy; print numpy.get_numpy_include 
()')

For now, they're in the site-packages directory, under numpy/core/ 
include. That position might change (it used to be numpy/base/ 
include, for instance), if we rename modules again. They probably  
won't migrate to the python include directory for the reason they're  
not in there now (non-root users can't install there).
