Before using revdep-rebuild, you need to do a -pW --clean to see what's old/obsolete on the system. It can clear lots of cruft after just six months of updates. Once you see what needs to be cleared, you can do an -a (ask) before remove. Saves you from the sytem pulling python and fragging portage. Once you've cleaned the system and updated things, then a revdep-rebuild shouldn't give you too many problems but if it does, keep in mind that a clean install doesn't take that long and you get the opurtunity to ensure that all of your flags (package u/mask) are all correct.
