What are "dependencies" here?
Can you provide a full recipe of what you are trying to do, including
your .sbclrc and the Lisp code snippets you've run to test this?

Does it work for the libraries installed with Guix?

This seems to be a red herring, as Guix does not change how CFFI loads
libraries.  The only thing that changes is where the libraries are found
with Guix packages.

Let's see what we can reproduce with your examples! :)
