[CentOS] Missing package

The big update caused one of the rare re-starts on my mail server, so I saw the startup messages that I had forgotten about.

Oct 28 10:50:04 borg2 python: [3424]: warning: python-dbus not installed. Oct 28 10:50:04 borg2 python: hp-systray[3424]: warning: Qt/PyQt 4 initialization failed. Oct 28 10:50:04 borg2 python: hp-systray[3424]: error: hp-systray requires Qt4 GUI and DBus support. Exiting.

I cna't find any package python-dbus. dbus-python is installed, but hp- systray doesn't recognise that as the same thing. Is it possible to create some sort of link so that when it attempts to call python-dbus it gets dbus- python instead?
