[gdal-dev] gdal compile from svn for python - how to specify a user defined numpy directory for compilation

I THINK the GDAL build calls python distutils (setup.py) to do the 
actual python extension build.

Ideally, the setup.py uses

numpy.get_include() to get the numpy include directory.

If so, it should "just work" with your setup, so I'd poke around and see 
if that's the case. If it is finding the numpy includes a different way, 
then that would explain your problem.

If it is set up this way, I'd track through the Python part of the 
build, and see how python is called, etc.

HTH,
