I forgot to notify about two things. Firstly, you will need version 1.0 of numpy. Version 0.9.8 didn't have the correct header files for backwards compatibility with old Numeric modules. Secondly, at the current time, at least for me, the numpy header files do not seem to be going in the right place with the numpy install (same thing has happend on my mac and linux). You'll have to copy or link the header files from python2.4/site- packages/numpy/core/include to include/numpy in the base pysparse directory from where you are building.
