I think this is a good use case for ‘trivial-build-system’.
Basically, with ‘trivial-build-system’, you just pass a Scheme
expression that produces the result. In your case that would be along
the lines of:
(begin
(use-modules (guix build utils))
(let* ((gh (assoc-ref %build-inputs "source"))
(perl (assoc-ref %build-inputs "perl"))
(out (assoc-ref %outputs "out"))
(bin (string-append out "/bin)))
(mkdir-p bin)
(copy-file gh (string-append bin "/gh"))
(patch-shebang (string-append bin "/gh")
(list (string-append perl "/bin")))
;; ...
))
> What directories should be created in the store?
$out/bin for the program, and $out/share/doc/grue-hunter for the license file.
> And how can I create such directories?
With the ‘mkdir’ and ‘mkdir-p’ procedures.

Avoid calling out to Coreutils. Guile and the (guix build utils)
provide us with everything we need to do that.
HTH!
