With the following near the top of my StumpWM init file, the
'load-module' function works like 'asdf:load-system':

--8<---------------cut here---------------start------------->8---
(let* ((guix-profile (pathname-as-directory (getenv "GUIX_PROFILE")))
       (module-dir (merge-pathnames "share/common-lisp/sbcl/" guix-profile)))
  (set-module-dir module-dir))

(load-module "ttf-fonts")
--8<---------------cut here---------------end--------------->8---
