Jan-Albert van Ree has released KDE 3.3 RPMs for White Box Enterprise Linux 3.0
I just finished rebuilding the RPM's for KDE-3.3 The Fedora Core 3 Test 1 RPM's were used, with modifications in kdemultimedia to include mp3 support. For the build I needed to update my libtools to 1.5.6, autoconf to 2.59 and automake to 1.9.1
These shouldn't be needed for installing, but are available from my repository as well. SRPM's are available as well.
Here's the addition to yum.conf to grab the files (personal section is for automake,autoconf and libtools, also contains other updates so beware) KDE-3.2.3 holds some non-core KDE packages as krecipes, krename, krefty and kaffeine (with all support libs) which are not needed for a basic KDE 3.3 install
Downloads might be a bit slow, as I'm on cable only (384kbit up), sorry
