Comment (by GarrettAlbright):

 Bumping this because I'd like to use it, but I'm just not smart enough
 about how compilers work to know where to begin on patching it as was
 discussed above. I'll put a bounty of US$20 out there for anyone that can
 get this installable on the M1 before the end of May 2021.
