I guess this is due to the "kst works with KDE 3.1" requirement, and I
wonder whether jumping right to KDE 3.4 from 3.1 is possible ? Note that
personnally, I try to have a somewhat up-to-date KDE installation and I
wouldn't mind but it seems that other users are more reluctant or have
more constraints...
