A thought on that: There is one strong(ish) reason to use a generic
BLAS_LIBS variable instead of enforcing use of a .pc file installed
with pkgsrc. When one builds pkgsrc with the Intel compiler suite (or
Pgi, for that matter, if that is supported in future), one usually wants
to tell pkgsrc BLAS_LIBS=-mkl to make the Intel compiler include the
optimized BLAS it ships with.

Alrighty then,
