I finally got back to trying to resurrect the RHEL6 tinderbox, However the xserver build is broken due to a double definition of DBusConnection http://tinderbox.x.org/builds/2014-09-19-0004/logs/xserver/#build This seems to be due to 480590b90c3966536451d2a2fecc42a66082ed77 dbus-core: Make dbus-core no longer mutually exclusive with udev Dave.
