I’ve got a bunch of new packages that I created because the latest one from Robby didn’t really work out for me. Not his fault, there was a bunch of bugs (plasma, panel, kwin) that were annoying me and because I like to live on the edge, I built some of them from SVN. I downloaded Robby SlackBuild script and use them against KDE SVN so if you want to run the latest and greatest, here are some package for KDE.
kdebase-800847-svn-i486-1.tgz
kdebase-runtime-800847-svn-i486-1.tgz
kdebase-workspace-800847-svn-i486-1.tgz
kdelibs-800648-svn-i486-1.tgz
kdepimlibs-800844-svn-i486-1.tgz
Note that those packages are build against avahi and openexr as I have them on my system. Also, those are very experimental so be warn. I will not take responsibility for your mistake except if you tell me they are working ok. 
Enjoy.
UPDATE: Forgot to mention that you probably need to removepkg kdebase*.tgz and then installpkg as the name of my packages aren’t kosher. I knew that but that’s just to make sure whoever installing them is aware of them being experimental. cough cough.
