Thanks for proposing a patch so quickly!

For me this looks confusing: The actual error message is not prefixed by
"ERROR:". Also (nitpicking) the explanation could by a bit more verbose.
Like this:

ERROR: In procedure scm-error:
ERROR: Package module "abc" does not exist.
ERROR: Please check the "use-package-modules" line in your configuration.

It would even be better is the fist line would not refer to "procedure
scm-error", but to the config actually processed (and even the line in
there). But nevertheless this patch is a big improvement already.
