I'll jump in just to suggest you NOT use gslapt to remove packages. As root, do
as M0E-lnx explained.
Gslapt is often too aggressive in removing dependencies along with packages. This can wreck your system. Using removepkg to uninstall packages is much safer as it removes just the packages. This could leave you with unneeded library files and other detritus, but that's better than messing up your system.
By the way, if you want a minimal KDE installation (desktop and konsole, among others), I concur with M0E-lnx that you'll get what you want if you install VL 6 Light and then use gslapt to install kdebase and kdelibs. Those will give you the KDE desktop, konsole, konqueror, and other KDE applications but not the multimedia stuff, games, graphics apps, etc., etc., which you don't want.
