I get an error about KDE not finding UIC plugins, but I know they e installed. Whats wrong?
This is almost certainly an installation problem, not a KDE code problem. A number of problems can lead to this, but most likely you have more than one version of Qt laying around and the configure script is calling a different one than KDE is using. Another thing that may help is to rebuild and reinstall your kdewidgets.so file, which is located in the kdelibs/kdewidgets directory. Note that if you *do* have multiple versions of Qt, this may compile against the wrong one. This problem creeps up on various mailing lists occassionally, so looking at the archives on lists.kde.org may be helpful.
