Leo means to add this to the file you have edited (lisp.scm).
Currently, there’s only

      #:use-module (guix download)

but you need to also add

      #:use-module (guix git-download)

if you’re using the ‘git-fetch’ procedure.  Because ‘git-fetch’ is
undefined otherwise Guile fails to load “lisp.scm” and this failure
cascades through everything else.

It would certainly be nice if the actual error would appear on the last
line instead of one of the errors resulting from not being able to load
“lisp.scm”.
