Great, welcome aboard!  :-)

Overall this looks good to me,

Actually srfi-1 is not needed because ‘alist-delete’ is re-exported by
(guix build utils), which is used by default.  So the #:modules argument
can be dropped altogether.

This works well, but it can be simplified as:

  #:tests? #f
  #:make-flags (list (string-append "PREFIX=" (assoc-ref %outputs "out")))

The description doesn’t contain a copyright statement in general.

Could you send an updated version with these changes in the format
produced by ‘git format-patch’, and using a ChangeLog-style commit log
(see ‘HACKING’ for details)?  That makes it easier to apply the patch.

Let us know if you have any questions.

Thanks!
