Looking at that thread they don't seem to see a problem. I haven't tackled
cblas-reference yet but I have made an ebuild to use the vectorize framework
from apple on OS X (I'll put it in the overlay soonish) and the test suite for
lapack-reference totaly failed when built with either blas-reference or
vectorize. I am guessing that it must be similar to what you got with
cblas-reference.
