 Replying to [comment:3 rkern]:
 > Well, it works for me on OS X 10.4 (Intel), Python 2.5, and scipy
 0.5.2.dev2329. Can you use nm(1) to determine if cephes_erf is actually
 linked into _cephes.so?

 I'd be happy to do that nm test, but not sure how to go about it.  I did a
 finder search for a cephes_erf file thinking I needing to do "nm
 cephes_erf", but didn't get any hits.  What am my missing?

 Also, I'm on a non-Intel Mac. I'll install and test python 2.5 right
 away—I'd completely forgotten that I'd had to use 2.4 instead for
 matplotlib.
