    I'd like to see if other Mac users experience the same issue.  We could
    increase the tolerance if it consistently fails by the same amount on
    multiple different Mac systems.

On my Fedora 19 (x86_64) it passes with reference BLAS  but fails with ATLAS
and OpenBLAS.


Could you please print out and post the actual error text?  Thanks.
