In G-golf ( https://git.savannah.gnu.org/cgit/g-golf.git ) in the

g-golf/init.scm

file, there's this line

(define %libgirepository (dynamic-link "libgirepository-1.0"))

and when running make, I get

In procedure dynamic-link: file: "libgirepository-1.0", message: "file not
found"

but both Gobect-introspection and Glib are in the ad-hoc environment
(they were found by configure)
