I don't think it is possible to cross compile numpy (or any extension
based on distutils for that matter) without bypassing the build system
and building it by yourself. Distutils does not support cross
compilation at all (except on windows for 32 vs 64 bits).

How did you build your 32 bits python on the 64 bits OS ?

cheers,
