My proposal: let the luarocks call a hook to check if the given
dependency is satisfied on the current system, or try to install native
package forst, like:

/etc/luarocks/hooks.lua:
function isInstalled(packagename, version)
  return false
end
function installNativePackage(packagename, version)
  return false
end

Then it would be the distro maintaners' (or just system's owner)
responsibility to return this information using their local packages
repository - using rpm, apt-get, pacman etc.
