zheevd is a LAPACK routine. Check for that symbol in the LAPACK library that you 
are linking. If it's not there, then your LAPACK library is broken. ATLAS 
provides some optimized LAPACK routines, and some distributions of ATLAS provide 
LAPACK libraries with *only* those routines:

Sorry, I don't think that Google Groups does mirroring like GMane does. While we 
will be migrating the numpy-discussion list away from Sourceforge, it will be to 
the server, not Google Groups.
