I'm using a Guix OS and I don't have the issue; StumpWM uses the
precompiled files and doesn't try to recompile anything.
Maybe we can try to find what is the difference between your
configuration and mine.

Are all the packages for the Lisp systems and StumpWM modules that you
load in your init file installed in your Guix profile?

How is your StumpWM started (.xsession file, custom script, ...)?

What is the result of evaluating '(getenv "XDG_CONFIG_DIRS")' in your
StumpWM?

What is the result of evaluating '(getenv "XDG_DATA_DIRS")' in your
StumpWM?

Could you share the part of your init file that sets the module
directory (or directories)?

Does StumpWM try to recompile every module that you load, or only
some of them?
