I'm not sure if it's due to as-needed, but I have a strong suspicion that it is.
I can't compile kdebase anymore, because when linking something in kicker it
finds /usr/lib/kdecore.so and /usr/lib/qt3/lib/libqt-mt.so instead of the ones
it should use ($KDEDIR/lib/kdecore.so and $QTDIR/lib/libqt-mt.so), which always
worked. The symptom was simply some undefined kdecore and qt symbols (because
the system kdecore is older and because my own qt is BIC on purpose), but
using -Q -v -Wl,-t in the link line showed that it was picking up the wrong libs
(in addition to the right ones further down).

Does this mean it's the installed kparts.so which doesn't pull in the right libs?
Or maybe the .libs/libkonq.so ?
Both show the right RPATH in objdump -p though....
objdump -p /mnt/devel/kde/kdecvs/build/kdebase/libkonq/.libs/libkonq.so | grep PATH
  RPATH       /mnt/devel/kde/kdedir/lib:/mnt/devel/kde/kdecvs/qt-copy/lib:/usr/X11R6/lib

Unlike the kdeui problem, installing libkonq doesn't help.
