The spec's well defined. It just tells you how := works, not how to use it in a sensible manner.

That's what I meant and what I miss in the kdebuild-1 > spec :-) Generally, it "just works", because packages are usually fairly good at picking up the best installed version themselves anyway. But yes, if you have to pass a version manually to a package, best_version is the way to do it. And no, that's not something that should be in the spec. The devmanual, perhaps, although there's no kdebuild stuff in there just now. -- Ciaran McCreesh
