Binaries that link with the Lua library already contain a copyright string:

%ident lua
lua:
     $Lua: Lua 4.0 Copyright (C) 1994-2000 TeCGraf, PUC-Rio $
     $Authors: W. Celes, R. Ierusalimschy & L. H. de Figueiredo $

I think we mean that you're not allowed to remove this from you binary.

In any case, there is no restriction on your final program; you can sell it
or distribute it freely, as you wish. Lua's license is not viral like GPL.
