The attached patch modifies AX_BLAS to detect the (free-software, BSD-licensed) OpenBLAS library, a descendant of GotoBLAS (http://xianyi.github.com/OpenBLAS/).

In my tests, OpenBLAS (which includes both the Fortran BLAS and also cblas, as well as LAPACK, in -lopenblas) has somewhat better serial and parallel performance than ATLAS, is vastly easier to install, and has some other advantages (e.g. OpenMP support, runtime architecture detection to switch compute kernels, ...). Hence my patch checks for it before ATLAS.

Regards,
Steven G. Johnson
