Looking through the README.md sections that mention Lua, it seems like
the ability to work with non-LuaJIT is not a priority.  E.g., "It now
runs again with luaffi under standard Lua 5.2 (and probably 5.1,
untested)."  ("Runs again" makes it sound like it worked for while,
lost compatibility, and maybe works again - does not inspire
confidence.)  Besides, buildroot does not [currently] have luaffi.  So
I don't think the Lua case is currently an option for a
buildroot-generated system.

but regardless ...

I wasn't aware of that - but the INSTALL_LMOD value does seem to imply
that.  Changing the path to /usr/share/lua wouldn't hurt, as the files
can go any place that luajit will search for them at run time.  So,
okay, I'll test locally and then submit a patch to change this.

Thanks,
