I was at that site yesterday after a bit of searching.
I was a bit confused arriving there after Google guided me to
the Intel kernel math site...(???)

http://www.intel.com/cd/software/products/asmo-na/eng/perflib/mkl/index.htm
Which is what made me think BLAS was non-free.

I am beginning to remember that I have used BLAS and LAPACK with fortran
before, but i didn't remember where I got them from.
I certainly didn't remember Intel being involved.
I thought that perhaps because I had used them with MSDOS they may have 
come from there.

Is BLAS not GPL?
