This is an English newsgroup, so I will reply in English:
You have written: "Installiert ist kde-3.5".
I doubt that this is true: How did you do this without using
~x86 keywords for the kde packages?
(Or did you use `ACCEPT_KEYWORDS="~x86" emerge kde'? This is a bad idea,
because emerge will then always try again to downgrade if you call it
without the ACCEPT_KEYWORDS variable. It is better to list the required
packages in /etc/portage/package.keywords with ~x86 - this will be
remembered by portage).

Both questions are answered in the above cited output:
libkipi-0.1.2 requires kdelibs. At least at this step (for libkipi-0.1.2)
the version of kdelibs plays no role as long as it is >= 3.1.
