DBusTubes must be integrated in telepathy-qt4 see: http://gitorious.org/drdanz-telepathy-kde/telepathy-qt4/commits/high-level-tubes+autotubes
Pretty sure this is now merged.
I think it's not, even though Dario promised me that it will be merged very soon. Most updated branch should be this: http://cgit.collabora.com/git/user/drf/telepathy-qt4.git/log/?h=dbus-tubes
Closing this! \o/
