qt3 bindings for the dbus IPC library. This is the old bindings package needed for KDE 3.5.4, but it works with dbus-1.x. If you want to build the newer bindings for qt3 (the ones that were backported from the qt4 bindings), this script should support that with a few modifications - see the SlackBuild script for more information. This requires the dbus package (available at SlackBuilds.org), and you will need to start the messagebus service prior to building this.
