So far the cl-asdf package in Guix is only used to update the ASDF
bundled in the sbcl, ecl, ccl and clisp packages, so that they all use
the same version of ASDF.

Instead of using 'require', it should work if you just load the file:

--8<---------------cut here---------------start------------->8---
(load (merge-pathnames ".guix-profile/share/common-lisp/source/asdf/asdf.lisp"
                       (user-homedir-pathname)))
--8<---------------cut here---------------end--------------->8---

Or you could use the sbcl from Guix instead of the Ubuntu one.
