Hey Marek,
It looks like I need to update the patch as it's failing to apply to
Makefile.am
In the meantime, you could try to apply the one failed hunk in
Makefile.am.rej yourself, that should fix the problem.
Another thing that needs a bit of fixing is that this doesn't work on fresh
Guix repositories, you need to have built Guix once from a repository
before applying the patch. I'll try and fix both of these problems as soon
as I get the time to, but once you've taken care of this it should work
smoothly.

Regards,
Sarthak.
