It is needed translation to Pascal...
No, it's not. Even though lua is small, translating the whole lua (it's interpreter + standard libs) is not a trivial effort. You can do as BigChimp said: link the lua library statically (well... even this one requires changes to the lua bindings). It's under MIT license, which is AFAIK means: "do anything with it as you wish, just don't (can't to be precise) charge the author if something goes wrong".
