I recommend you get it from: http://lua-users.org/wiki/BlitzMax
You'll need to download Lua 5.1.2 from http://www.lua.org (I believe the latest version works with BlitzMax, but I'm not sure.) Put lua.bmx in /mod/axe.mod/lua.mod, and Lua in lua-5.1.2 under that folder, then Build Modules, and you should be all set.
