I have recently encountered the same problem. According to this error happens
when the environment variable SBCL_HOME is not set (This can be checked
with "C-t : (sb-ext:posix-getenv "SBCL_HOME")", which will return nil if
SBCL_HOME is not set).
When running "(sb-ext:posix-getenv "SBCL_HOME")" in a separate sbcl REPL
however it returns "/gnu/store/...-sbcl-1.3.7/lib/sbcl", which explains
why the error only appears in stumpwm.
To work around this problem I added
"(sb-posix:putenv "SBCL_HOME=/home/diego/.guix-profile/lib/sbcl")" to my
