Yes, I saw that you moved the old guix to guix-command which sounds
great and works here. Sadly, 'M-x guix' gives me a backtrace ...

Debugger entered--Lisp error: (error "Autoloading file /home/glc/gom/.gpm/gfg/emacs-guix/emacs-guix/elisp/guix-command.elc failed to define function guix")
  autoload-do-load((autoload "guix-command" "Popup window for 'guix'." t nil) guix)

... with this emacs-guix config ...

Oh, DUH! Thanks!
