Скомпилировал kdelibs 3.1 & kdebase 3.1 gcc 3.2.1
$export CFLAGS="-march=pentium3 -mcpu=pentium3"
$export CXXFLAGS="-march=pentium3 -mcpu=pentium3"
$./configure -prefix=/usr/local/kde -disable-debug --with-alsa -enable-objprelink
$make
$make install

и все кдешные проги из kdebase валят в stderr:

обновил из cvs:
$cd kdelibs-3.1
$export CVSROOT=:pserver:anonymous@anoncvs.kde.org:/home/kde
$cvs login
$cvs update
$cd kdebase-3.1
$cvs update

перекомпилил и все равно не запускается.
