Hi, all you have to do is
1. Update to slink (I have done so and it worked well - it may also work with some updated hamm-packages but I don't know) 2. get qt1.42 from slink/potato 3. get the *.deb files from ftp.[de.]kde.org/pub/.../dists/deb/potato/binary-i386/ 4. install them with dpkg -i [names].deb (include your downloaded qt1.42) On my system everything worked fine. Good luck, Andreas.
