I'd say to always use the project name.

I think we should provide lua and lua51 packages with as much as
possible built using the lua (5.2) package and the rest built for lua51.
 That may mean we need to provide lua51 versions of libraries too for
the transitional period.

If you create the rebuild list and send me the PKGBUILDs for lua and
lua51 - and anything else in [extra] that immediately needs done - I
will build them for [extra].
