Hm, that log message can indeed be more helpful. I opened a ticket
about this:
https://trac.torproject.org/projects/tor/ticket/11043
Feedback is welcome.

For what it's worth, the easiest way to set up the Extended ORPort is
to put:
'ExtORPort auto'
in your torrc. Tor will figure out an appropriate port number for you.

The Extended ORPort is used for statistics gathering for now. In the
future it will be used for more functionality (to orchestrate rate
limiting, etc.). See Kostas' mail for more information.
