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. Francois
