I'm having problems compiling any KDE-dependent software right now (Superkaramba and KDE themes, mostly). The error I'm getting is:

/opt/kde/lib/libkdecore.so: undefined reference to `KStyle::defaultStyle()'
/opt/kde/lib/libkdeui.so: undefined reference to `KPixmap::~KPixmap [not-in-charge]()'
collect2: ld returned 1 exit status
make[3]: *** [superkaramba] Error 1
make[3]: Leaving directory `/var/tmp/portage/superkaramba-0.36/work/superkaramba-0.36/src'
make[2]: *** [all-recursive] Error 1

I Googled the problem, and the Arch Linux forums had a suggestion to reinstall kdelibs. I did that, even updating from KDE 3.3.2 to 3.4.1, and it's still the same error message.

Any suggestions?

Possibly relevent information:
Celeron 1009MHz
nVidia GeForce something or other
Slackware 10.1
have tried superkaramba 0.35, 0.36, 0.37-RC1...all fail. KDE themes (keramik with transparent kicker and liquid) are other attempts that fail with the same error.
