You know, I knew this sounded familiar. If you regularly build against MKL,
can you send me your site.cfg. I've had a lot more success getting the
build to work using the autodetection than the blas_opt and lapack_opt
sections. Since the autodetection doesn't seem like the accepted way, I'd
love to see how to get the accepted way to actually work. :)
