Comment(by lhorner@…):

 The following statement from http://math-
 atlas.sourceforge.net/errata.html#G4gcc makes me think that the problem is
 single cpu vs multiple cpu/core.  Has anyone had a failure on a dual-G4 or
 G5?

 "libptcblas.a
 The ANSI C interface to the threaded (SMP) BLAS. This library only appears
 if you have asked for SMP support."
 also
 "The full LAPACK library created by merging ATLAS and netlib LAPACK
 requires both C and Fortran77 interfaces, and thus that link line would
 be:
    -L$(MY_HOME)/ATLAS/lib/$(MY_ARCH)/ -llapack -lf77blas -lcblas -latlas
 If you wish to use threaded BLAS, you simply indicate those interface libs
 rather than the sequential. The above line for SMP would be:
    -L$(MY_HOME)/ATLAS/lib/$(MY_ARCH)/ -llapack -lptf77blas -lptcblas
 -latlas"

 It looks to me like atlas should be looking for libptcblas.a on my
 Powerbook G4.
