For the Common Lisp libraries to be found, the XDG_CONFIG_DIRS and
XDG_DATA_DIRS environment variables must contain the paths to the
profile where the libraries are installed.

Something like:
--8<---------------cut here---------------start------------->8---
XDG_CONFIG_DIRS="/home/username/.guix-profile/etc:..."
XDG_DATA_DIRS="/home/username/.guix-profile/share:..."
--8<---------------cut here---------------end--------------->8---

These variables are set automatically when sbcl is installed in the
profile (they can be set by some other programs too).

If you don't want sbcl in the profile, one or both variables might not
contain the paths to the profile, and your guix-home config has to put
them in. I've never used guix-home yet, but I suppose
home-environment-variables-service-type can do that, and then creating
a custom ".config/common-lisp" directory should not be necessary.
