I would absolute *love* to get proper linear algebra libraries.
With proper I mean that areas such as eigenvalue computations
and singular value decomposition is included.

The license of GSL is of course a problem. The readline
solution doesn't really fit well in this context.

However GSL is not the only matrix library out there. LAPACK (
http://www.netlib.org/lapack/) has license that fits better.

The code is in Fortran 90 though, so it might be harder to
translate directly. That said, it might make sense to
go the FFI-route for matrix computations. Getting the details
right for the more advanced algorithms is hard, very hard.
