It looks like we may be on the hook for some c++ ABI breakage with
Apple's latest OS (Snow Leopard). See the attached email forwarded from
the numpy mailing list.

Looks like C++ code, and snow leopard has gcc 4.2, which is likely to
have some subtle ABI incompatibilities with 4.0 (the one from
leopoard). So yes, a matplotlib rebuild would be the first thing to
try.
