Please be aware due to the way Luarocks is designed any binaries installed
via Luarocks-5.2 AND 5.1 will overwrite each other in #{HOMEBREW_PREFIX}/bin.
This is, for now, unavoidable. If this is troublesome for you, you can build
rocks with the `--tree=` command to a special, non-conflicting location and
then add that to your `$PATH`.
