No-one's doing Void yet. Actually we only have stuff for FreeBSD and OpenBSD right now. I'm not 100% familiar with how Void Linux packaging works, but it looks to me (from looking at this) like it's not too complicated. Feel free to start making some packages.

If you can get them added to the main repository in Void, that would be great too: that's the end goal. I don't know how difficult that is, I guess for Void you just send a PR to their GitHub repo.

If you want to know what has been packaged so far, look at the TODO files in the repo. If you want to get push access to the repo, post your SSH key and z3bra (who runs the git AFAIK) will probably add you.
