It is installed and works fine; except that it does not start xfconfd.
Surely there must be something that tells dbus where Xfce config
files are?

I do not have that directory at all, so how could that help?

startxfce4 script stops with the error mentioned earlier when xfce4-session
can't communicate with xfconfd. It is not possible to start Xfce at all 
by using
the script. The script does not start xfconfd. I added call to it and 
got things
working, but I do not believe this is how it is supposed to work.
