Comment(by pv):

 The point of crash above is in a `scipy.linalg.fblas` routine. It seems to
 me that the Veclib wrappers in `scipy/linalg/src/` are in fact incorrect
 --- `src/fblaswrap.f` calls directly the ZDOTC routine, and not the CBLAS
 wrapper in `src/fblaswrap_veclib_c.c`.

 The solution is probably to replace these wrappers with the ones from the
 arpack package.

 That would then leave the CLADIV issue to be solved. For that, can you
 locate the `clapack.h` in your Veclib installation and attach it to this
 ticket? Or, any other header file in the Veclib include directory that
 contains the string 'cladiv' lower or uppercase.

 (Damn, I'd really need to get my hands on an OSX machine -- I'm sure
 debugging via Trac is frustrating to all parties :)
