emerge world will reinstall most packages

[ugoebel]

I tried to do an upgrade to kde 4.1 as described in the upgrade-guide "http://www.gentoo.org/proj/en/desktop/kde/kde4-guide.xml".
After the command "emerge -C $(qfile -C -q -e /usr/kde/4.0)" and fixing some blockers (sorry, I do not now anymore what packages I fixed) I would start an "emerge world".

Now it will reinstall almost all packages. If I restart the emerge (because of an error) it will reinstall again all packages also those which are already installed. I fear that there are somwat no more correct. Can anybody help me.

Here are some infos:

saturn etc # emerge -pv world

These are the packages that would be merged, in order:

With portage-2.2*, "emerge world" does what it says, it will emerge all packages listed in your world file.

If you only want to emerge packages that need updates, then try "emerge -u world" instead.

[notHerbert]

Also you can use emerge --resume -av and emerge --resume --skipfirst -av to restart an interrupted emerge.

Sorry, so far I have not read the docu for the new portage-version. Now I have installed kde 4.1.
Thank you for your immediate help.
