I don't want to confuse the discussion here, but the OS X ada list
(www.macada.org) has been discussing this lately, (as well as
December, 2007 if you're inclined to dig through archives).

The upshot is that the file i-forbla.adb is edited to comment out one
line, so that after the edit we see this:

--  pragma Linker_Options ("-lgnalasup")

All I did then was to compile a "hello" program using -a that with-ed
Ada.Numerics.Long_Real_Arrays and Ada.Numerics.Long_Complex_Arrays,
then copied the new .o and .ali to the proper Ada library directory. I
can supply more details if needed. Also, I don't pretend to understand
why this works.

Incidentally, BLAS and LAPACK, both Fortran and C versions, come pre-
installed on OS X so linking to them is pretty trivial.
