Hi y'all,

This is both a patch submission and a call for help—I'm far out of my
waters with this package and am not sure of the proper Guix-y way to
build it.

So the build sequence for Guile GSL is:
(1) Compile a bundled libguilegslblas.so with a C compiler, using the GSL
    libraries from package inputs.
(2) Put proper paths to the GSL libraries and libguilegslblas into the
    Scheme files.
(3) Compile Scheme files as per guile-build-system.

I've got (2) and (3) more or less working. The problem is: which build
system should I use and how do I synthesize GNU build system (makefile,
libguilegslblas.so, (1)) and Guile one?

You can find my draft (doesn't build and is not usable in general) patch
attached below. Any help appreciated!
