Thanks again, David. I was able to use a solution from Ricardo to get guile-gi to run under guix, but it didn't work for g-golf. :-( Even so, I was serious about wanting to help you out. My Ubuntu system has guile 3.0.7, which I hope would be OK. For g-golf, would you recommend I clone your github repo and compile it . . . ? I can give that a try. I'm not entirely sure that packages installed by guix won't interfere, and I don't yet know how to uninstall guix, but I'll give it my best shot for you.

This is a guix problem, reported a few years ago already by one of my
first g-golf user, the author of the nomad package. I have no idea why,
nor what it takes to fix this in guix, but this error is the symptom
that you (guix, not you nor g-golf) is trying to load the Gdk typelib
more then once, which is 'unauthorized', by (GNOME) design.
Until what causes this error is fixed, absolutely nothing can work.
I am on Debian, where all examples work [1]

This is the symptom that you are running a g-golf version that was
built from the devel branch - where as this is generally ok, I am also
very cautious to what I push even on the devel branch, I am in a process
of re-designing re-writing the way users may register new classes, that
inherit from GInterface. I also am re-designing re-writing how users
interact with VFunc. For these reasons, I recommend the guix team
to stick to the latest commit of the master branch for now.
The hello-world example has worked 'fine', on Debian, for many years,
you don't need the latest commit to run it :) - though in January
2021, I updated it (as well as other examples) to use Gtk-4.0.
I see Ricardo also answered and tried, I'll also comment his
message(s) ...
David
[1] in addition to what you need to install g-golf, to run the
examples, you also need to install gir1.2-gtk-4.0:amd64 (or
gir1.2-gtk-4.0:xxxx for another architecture, which content is listed
below, fwiw:
dpkg -L gir1.2-gtk-4.0:amd64
