Well, it appears that the missing symbol was due to some bad combination
 of ACML _and_ ATLAS.  Removing atlas and recompiling scipy/numpy
resolved it.

As far as the original crash goes, my problem was that I had the int64
version of ACML installed.  So for you ACML users out there, don't use
the int64 version unless the code you're using actually uses INTERGER*8.
