[Cooker] Chinese fonts source requires ttindex from VFLibs package... but where's the package?

[John Cavan]

Not that I actually need to rebuild this package, it just happened to be
in the mass build group, but it seems to require a package that does not
exist in either cooker, Air, or contrib: VFLibs. No big deal, but how on
earth was this built in the first place? :o)
