The reason folks aren't talking about using NEEDED is that NEEDED data is generated _after_ building; getting the info into the resolver up front allows for a helluva lot more options, and makes stuff like ensuring you have all sources required downloaded *prior* actually simple to do, rather then inserting recalculating hacks into the resolver. Clarifying the 'recalculating', what you're suggesting is effectivelly unbounded resolution, re-calculating at each step. That route is *very* nasty since you can't gurantee up front the resolution will work, let alone ensuring the bugger doesn't go cyclic. ~harring
