Yes, it does. It needs the first ax_blas pass to fail, and then it should try
"blaswrap.o -framework vecLib".
I've actually learned a lot about the BLAS issue, *and* about dynamic library
handling in OSX, studying this. Armed with this info I've basically written an
entirely new blas wrapper (I'm calling it vecLibFort). It fixes *all* of the
offending BLAS and LAPACK calls (hopefully all of them), using a combination of
static and dynamic replacement. It also provides the ability to patch
*compiled* applications using the Mac equivalent of LD_PRELOAD
(DYLD_INSERT_LIBRARIES). It's also a lot more compact thanks to some
preprocessing tricks.
I think it's something that would be of great benefit to the wider Mac
community; I know there are other Homebrew projects that have latent bugs due
to the gfortran/vecLib incompatibility.
If you'll hang just a bit longer, I'll let you know when that code is ready to
check out (likely tomorrow).
