I have it using both. lua 5.4 is required, and lua 5.1 support is
included in the package if lua51's already installed.

Looks like it builds its own, plus a "lua-compat-5.3" tarball.

It might be possible to build neovim with lua 5.4. Worth looking into
at least. Ideally, it shouldn't be tied to an old version of lua.

The "vis" editor also uses lua-lpeg. It builds with lua 5.4 and seems
to work OK.

Yes, please do. Let me know what you find out.

Worst case scenario: if neovim really needs a lua-lpeg built with
lua51 support, list them both in REQUIRES, with lua51 appearing before
lua-lpeg, and mention it in the README. Also maybe add a bit of code
in the script that actually checks for the lua51 lpeg.so module, and
stops the build if it's missing.
