Thanks :-)

The current Emacs-Guix release (0.5.1) already has a fix for it
("processes" is bound to "o" there), so it looks like you installed some
previous version of emacs-guix with guix.  Make sure your guix is
up-to-date.  Have you ever run "guix pull"?

No problem, I just tried to describe this problem.

I think guix should either install its guile dependencies to the pulled
profile (as it does with any usual profile), or make an auxiliary file
with "Guile load path" environment that can be used both by
"~/.config/guix/current/bin/guix" and by Emacs-Guix.
