I asked Martin to explain how to do this on the rsync web page or better yet
put a prompt for it there but he hasn't said he would or not.

No, I really don't see how it would be possible for rsync to print that
error.  I also see no occurrences of the string "bind:" or "bytes :".
What's the simplest command you can run to repeat the problem?  Often just
the process of narrowing down a problem points to the solution.
