For this particular problem, the correct solution is to fix the lua port by renaming it to lua53 and making it install its headers to a directory that is not ${prefix}/include (and its libraries to a location that is not ${prefix}/lib), just like the other lua ports already do.

I have run into this same problem with another port I'm working on that still requires lua 5.1. I'm having to patch its build system to tell it exactly where to look for lua 5.1.
