I haven't used it for a long time, so its behaviour may have changed/improved. The last time I used it I got a *very* long list of "package XXX was added to your world file" kind of message and stopped using it ever since. I may have run it the wrong way - not sure - but thought of warning Grant just in case. With a back up in hand, which I foolishly did not have handy as I was rushing at the time, it is easy to revert any unwelcome changes. As Dale mentioned my original problem (a fat/polluted world file) would have been easily resolved if I used 'emerge -1' each time I manually tried to sort out some portage output. I think I've learned this lesson well. ;-) -- Regards, Mick
