Hello, Antero
I’ve also been involved in packaging Lean4, have you had any more progress on this? I tried to build guix from your patch, but `./pre-inst-env guix build lean` gets stuck at some point after trying to compile things for ~7 hours. I believe it gets stuck at compiling gash. Any clue?
Regards,
Divya Ranjan
