The usual bug-guix@gnu.org list will do just fine I would say.

In any event, I'm cc'ing the patch list with a quick patch that
updates the package which builds fine for me locally; I didn't test
running it though. I also updated to gexps and removed the
native-inputs label. Since this was an update and the package
currently doesn't build, I put it as one patch, but maybe it should be
split up? I'm not sure (I think usually as separate commit, but here a
fix/update for broken package seemed opportune), feel free to chime in
anyone. I also did this super quickly, apologies for any silly
mistakes.

Thanks for the report!
John
