kde 2.1.1 install question

I'm trying to upgrade my suse 7.1 box to kde 2.1.1 I downloaded the base binaries from suse, but when I try and upgrade I get the following error: root@truffula:/home/kwythers/tmp/kde2 > rpm -Uvh *.rpm package koffice-devel-2.0.1-5 (which is newer than koffice-devel-1.1beta1-19) is already installed package koffice-2.0.1-5 (which is newer than koffice-1.1beta1-19) is already installed file /usr/lib/qt2 conflicts between attemped installs of qt-2.3.0-44 and qt-experimental-2.2.3-10 I'm a little nervous about using the --force option. What should I do? Kirk
