Comment:

 I changed the default compiler to gcc48 in between (which is the standard
 default on Macports now), but I don't think this is the issue.

 It is probably some vectorization flag I don't get on my machine. With
 some googling, it seems that removing the -march=native flag could do the
 trick, as shown in the attached diff.

 If that works, I would be grateful if you could confirm and perhaps attach
 your openblas_config.h file, as it seems to come from flags I can't test
 with my hardware.
