Which is much better because it's handled directly with the PM and not eutils going looking in vdb by hand, right. In that case we should really encourage this and make built_with_use die or at least emit a qa warning? The only downside is that use deps don't support the --missing stuff and we'll see how big problem this turns out to be in practice... Caster
