It is.

guix-load-path is a variable defined in `guix-backend.el'.
Its value is "~/src/gnu/guix/emacs"

--8<---------------cut here---------------start------------->8---
guix-helper-file is a variable defined in `guix-backend.el'.
Its value is "/home/mthl/src/gnu/guix/emacs/guix-helper.scm"
--8<---------------cut here---------------end--------------->8---

These two variables helped me figure out that the problem was the use of
“~” in:

  (let ((dir "~/src/gnu/guix/emacs"))
    ...

When changing it with “/home/mthl” it works!  To avoid this kind of
mistake in the future, a simple fix would be to change the example in
the documentation, with:

  (let ((dir "/absolute/path/to/your-guix-git-tree/emacs"))
    ...

But is there a way to change the implementation to let users use
relative path?

Thanks,
