I tried to install Koffice Kpresenter 1.2.1 from ftp://download.us.kde.org/pub/kde/stable/koffice-1.2.1 I am somewhat confused by the readme. I have a Debian testing system with KDE 3.0.5a, kdelibs4?. The Koffice package depends on kdelibs3 which I think is KDE 2.2.x stuff.
From the readme: --info about the current KOffice 1.2.1 Debian packages ----------------------------------------------------- These packages are built with the current stable KDE release, that means KDE 3.0.x. Greg Madden
