A little remark so that everyone can follow: Luarocks compiles the
binaries on the user's machine, it doesn't distribute binaries per se.

Indeed, but I think it's way too complex for the average user... That
means your package will remain a marginal experiment (which is a pity).

On my machine LuaTeX finds the rocks without changing anything... I have
Debian/Sid with a vanilla luarocks.

executing luarocks would mean having luarocks in the
shell_escape_commands, which is certainly not an option... But users
could add the path to CLUAINPUTS, I think that's the safest option.

Indeed...

Thank you,
