How to update KDE 3.1.2

Hi, I have one question... How can I update my KDE 3.1.1 to KDE 3.1.2 ..I tried before just download packages and use rpm -U .... but there were problems with dependencies, and file conflicts....so what is the easiest way how to update ? I just want to update only pakcages which I have installed now....nothing more...is there any way how to do it with YAST ? (I have SuSE 8.2) thank you, Julo Chrobak
