Slackware 13.1 uses Ruby 1.9, and this could be the
cause
of the
problem (IIRC there were reported issues between Ruby 1.9
and KDE
3.5.10).
Yes, I remember the discussions. The recommended fix was to create two sym links. My build
scripts create them but I verified both do in fact exist. Further, Amarok needs the same
links and that package built without error.
