Overall it looks like it should work. I've attached your package from
paste.debian.org for anyone else reading along.

It sounds like you hadn't yet registered your package module in
'gnu/local.mk'. If you want to add a new source file to Guix, you need
to register it there so that Make knows to build it. For example:

https://git.savannah.gnu.org/cgit/guix.git/commit/?id=6cf2ac3cd6a42ded34814ac9120c7637cf3f8c7f

It's hard to know exactly what went wrong here; we'd need a patch of your
changes and the Git commit you are working from in order to reproduce
the issue.

But, I think you should try again adding a new module and registering it
in 'gnu/local.mk'.

Yes, this shouldn't have any effect on your issue. It's warning you
about an incomplete locales setup. Instructions on finishing the setup
are here:

https://www.gnu.org/software/guix/manual/html_node/Application-Setup.html#Locales-1

Basically, you'll need to export GUIX_LOCPATH in the environment where
you use Guix, and where the guix-daemon runs (that's why you see the
warning twice).
