I've moved to FreeBSD some days ago and I found that the GNOME 3 port working in progress doesn't work due to the broken gnome-settings-daemon.

The output is: 
        ** (gnome-settings-daemon:59891): WARNING **: Failed to get session for pid: GDBus.Error:org.freedesktop.ConsoleKit.Manager.GeneralError: Unable to lookup session information for process '59891'

And then it just aborts. I just want a workable GNOME 3 on FreeBSD. (Only one man is working on porting GNOME3 now)
