I am pleased to announce that LuaJIT 2.0 now compiles and runs on iOS version 3.0+, thanks to Mike Pall who has sacrificed his precious time for us - iOS developers. You will need fetch latest changes from GIT to proceed with iOS build, see: http://luajit.org/download.html
Please follow instructions at doc/install.html#ios of your working copy.
You may also use the script of mine below to produce complete universal library for both simulator& device (armv6& armv7). Place the script below in your GIT working copy. Once executed you will find "iOS" subdirectory containing both headers and libluajit.a universal static library.
Just copy them into your Xcode project and include "lua.h", "lauxlib.h", "lualib.h" in your Prefix.pch.
