Make roundup-server EACCES errors clearer If roundup-server is run on a priv port without privs (i.e. non root) it just returns: [Errno 13] Permission denied make this case clearer by reporting: Unable to bind to port 70, access not allowed, errno: 13 Permission denied so it points to the port bind operation as failing.
