Hello,
when I run 'emerge -uDtaN @world' portage re-emerges following packages again and again:

Code:

[ebuild  rR   ~]  media-video/cheese-3.6.2
[ebuild  rR   ~]   media-libs/clutter-gst-2.0.0
[ebuild  rR   ~]   media-libs/clutter-gtk-1.4.2
[ebuild  rR   ~]    media-libs/clutter-1.12.2


Is there an option to find out, why portage wants to re-emerge this packages even it re-merged it the last run?

First, post the full output of 'emerge -uDpvN @world'.

Code:

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

The packages need to be compiled against a new version of a library which was only updated after their last emerge.
If it really were the last packages emerged in the last run, this is a bug in portage, but probably another package was emerged after them which requires the rebuild.

It seems, there is really a problem/bug in portage.

I guess I've found the problem. I've un-installed 'media-video/cheese' to check what happens re-installing it via 'emerge -uDpvN @world'
That's the first time portage complains about insufficient dependencies.

Code:

!!! Multiple package instances within a single package slot have been pulled
!!! into the dependency graph, resulting in a slot conflict:

media-libs/cogl:1.0

  (media-libs/cogl-1.10.4::gentoo, installed) pulled in by
    media-libs/cogl:1.0/9= required by (net-im/empathy-3.6.3::gentoo, installed)
    >=media-libs/cogl-1.9.6:1.0=[introspection?,pango] required by (media-libs/clutter-1.12.2::gentoo, installed)
    (and 4 more with the same problems)

  (media-libs/cogl-1.8.2::gentoo, ebuild scheduled for merge) pulled in by
    (no parents that aren't satisfied by other packages in this slot)


Checking 'media-libs/cogl' shows, it shall be downgrade because I've removed it from 'package.keywords' by accident.
After include 'media-libs/cogl-1.12.2' in 'package.keywords' portage want to re-emerge (and update) the mentioned packages one time.

Code:

emerge -auDtNq1 cheese
[ebuild  rR   ] net-im/empathy-3.6.3
[ebuild  rR   ] x11-wm/mutter-3.6.2
[ebuild  N    ] media-video/cheese-3.6.2
[ebuild  rR   ]  media-libs/clutter-gst-2.0.0
[ebuild  rR   ]  media-libs/clutter-gtk-1.4.2
[ebuild  rR   ]   media-libs/clutter-1.12.2
[ebuild  r  U ]    media-libs/cogl-1.12.2 [1.10.4]


The next run of 'emerge -uDpvN @world' shown nothing anymore. :)

It seems portage becomes confuse, if a package shall be downgraded which would raise a 'multiple package instances' error...

I had this same problem and finally decided to do something about it :) ; re-emerging cogl did not solve this. After some experimentation I found the problem to be an old library version, libcheese-gtk:
Code:
TitanGentoo2 ~ # revdep-rebuild --library /usr/lib64/libcheese.so.3
 * Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries using /usr/lib64/libcheese.so.3
 * will be emerged.

 * Collecting system binaries and libraries
 * Generated new 1_files.rr
 * Checking dynamic linking
[ 65% ]  *   found /usr/lib64/libcheese-gtk.so.21
[ 100% ]                 
 * Generated new 3_broken.rr
 * Assigning files to packages
 *   /usr/lib64/libcheese-gtk.so.21 -> media-video/cheese
 * Generated new 4_raw.rr and 4_owners.rr
 * Cleaning list of packages to rebuild
 * Generated new 4_pkgs.rr
 * Assigning packages to ebuilds
 * Generated new 4_ebuilds.rr
 * Evaluating package order
 * Generated new 5_order.rr
 * All prepared. Starting rebuild
emerge --complete-graph=y --oneshot  --quiet-build=n --complete-graph=y --with-bdeps=y  media-video/cheese:0/7
..........
Calculating dependencies... done!

>>> Verifying ebuild manifests

>>> Emerging (1 of 1) media-video/cheese-3.6.2
I first checked that no program depends on this library:
Code:
TitanGentoo2 ~ # revdep-rebuild --ignore --library /usr/lib64/libcheese-gtk.so.21
 * Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries using /usr/lib64/libcheese-gtk.so.21
 * will be emerged.

 * Collecting system binaries and libraries
 * Generated new 1_files.rr
 * Checking dynamic linking
[ 100% ]                 

 * There are no dynamic links to /usr/lib64/libcheese-gtk.so.21... All done.
After removing both libraries, revdep-rebuild now finally finishes without rebuilding cheese:
Code:
TitanGentoo2 ~ # rm /usr/lib64/libcheese-gtk.so.21
TitanGentoo2 ~ # rm /usr/lib64/libcheese.so.3
TitanGentoo2 ~ # revdep-rebuild
 * Configuring search environment for revdep-rebuild

 * Checking reverse dependencies
 * Packages containing binaries and libraries broken by a package update
 * will be emerged.

 * Collecting system binaries and libraries
 * Generated new 1_files.rr
 * Collecting complete LD_LIBRARY_PATH
 * Generated new 2_ldpath.rr
 * Checking dynamic linking consistency
[ 100% ]                 

 * Dynamic linking on your system is consistent... All done.

An interesting lesson in Portage; this however was actually the first I had to manually remove an old library, although portage does inform you always about that...
