Hey, thanks for responding Guillaume, and thanks for forwarding, Pierre.

When I try this, I get this error:

Error opening #P"/gnu/store/j6s3hhmlm8n7ynv92agcbzzxrc0bgpc0-stumpwm-20.11-lib/lib/common-lisp/sbcl/stumpwm/package-tmpAAURS01.fasl

which is a file that does not exist.

This is what I mentioned above, pointing to the `share/` side of things.
On my Guix OS system, this works (but it has to compile everything; I'd
prefer to use the precompiled fasls), but on my alien distro, I get the
afforementioned permission error as it tries to write to the store.

I'm happy to try and find something that works in the short-term so I
can get my window manager back, but in the long-term, we should repair
the bug so that new users aren't left wondering as well.

Thanks again for responding.
