I am confused, scipy does not use blis.
It tests libblas, openblas and atlas but blis was so far I know never
configured as a blas source in the tests.
Unless something has changed with those packages that they pull blis
this might be a false positive.

If blis is ready enough to be used prime time, let me know we can add it
to numpy's and scipy's testsuites.
