Ouch, this is a bug!  Sorry and thank you for the report!
It should be fixed by the latest commit:

  
https://notabug.org/alezost/emacs-guix/commit/d7b54784bc3962570519aac472f54598c10299ae

So you may try to reinstall it from MELPA to check if it works now.  BTW
installing from MELPA should be as fine, as from Guix.  As far as I
understand, the problems you faced are not related to the way you
install Emacs-Guix.

Yes, this is a big problem on non-GuixSD systems.  In short, "guix pull"
does not install its guile dependencies in the pulled profile.  Instead
they are hardcoded in "~/.config/guix/current/bin/guix", so Emacs-Guix
can't use these modules and this leads to unexpected errors.

The only workaround is to install "guix" in a user profile: this will
automatically "propagate" (install) all the missing Guile dependencies.

People usually don't face this problem on GuixSD because "guix" (thus,
all its propagated dependencies) is installed in a system profile there.

I don't see a way to fix this problem on the Emacs-Guix side.  For more
details, you may look at the discussion at
<https://github.com/alezost/guix.el/issues/28>.
