That should in fact clean anything that's not in world and is not a dependency (might it be directly or indirectly) of a package in world. If emerge --depclean --ask doesn't report it on the output list, then there's something depending on qt3 installed. Remember that setting USE="-qt3" doesn't magically remove the dependency on qt3 for those programs that needs qt3. Kde 3.x relies in qt3, and no USE flag can change that. USE flags only change optional settings, for kde 3.x qt3 is not an option. However, most people don't usually care about sanity, and in that case, you should be careful when using --depclean. -- Jesús Guerrero <[EMAIL PROTECTED]>
