All I can say is that that is all I installed and portabase worked from a menu icon which appeared after a reboot. Did you give it a try?Isn't the package "qt-3.3.8.pet" the correct one?
My view is that if it doesn't work, then something may have gone wrong with the installation of qt-3.3.8, or there may be some other drama with it..... If it works, let it complain about dependencies if it wants to
Sorry, I'm not much help
