If I remember correctly, mpl 0.87.6 is compiled against numpy-1.0.rc2, 
but rc3 has since come out with a C-API change so that it will not work 
with 0.87.6. So, give numpy-1.0.rc2 a try.  numpy 1.0 is scheduled to 
come out soon, and I expect that shortly thereafter there will be an mpl 
release to match it.  At that point the numpy C API should be genuinely 
stable and it should no longer be necessary to keep future mpl and numpy 
versions in lockstep.
