I do not know if it is the best but I do:

  guix build -L path/to/clone the-package
  guix install -L path/to/clone the-package -p /tmp/test
  /tmp/test/bin/the-package


Otherwise, I put in a channels.scm file something like:

--8<---------------cut here---------------start------------->8---
(list
 (channel
    (name 'kikoo)
    (url "file:////home/simon/path/to/clone")
    (branch "master"))
 (channel
  (name 'guix) ; avoid to recompute heavy derivations and build modules
  (url "https://git.savannah.gnu.org/git/guix.git";)
  (commit "000c7a0f70248ccf9dc774ef23da3e26d142c610"))
--8<---------------cut here---------------end--------------->8---

where commit is something I already have in /gnu/store, then:

  guix pull -C channels.scm -p /tmp/loc
  /tmp/loc/bin/guix install foo -p /tmp/test

but it is less convenient.


All the best,
simon
