using matlisp core to link to fortran library

Hi,

I have compiled a bunch of Bessel function routines for complex
arguments from netlib/amos into a shareable library, and would like to
link to them from cl (sbcl for now).

Instead of reinventing the wheel, I would like to use matlisp's
capabilities to link to these libraries.  Can someone point me to the
important (mat)lisp files where I can find the necessary
functionality?

Once everything is said and done, I would put up a summary that could
be useful for others.

Thanks,

Mirko
