Comment (by jmr@…):

 The copyright file says that you may not distribute the software without
 getting the author’s permission. The above quote says Debian has done
 that. We have not (yet). If we were to get permission for MacPorts to
 distribute it, `Restrictive/Distributable` would be the most appropriate
 license value. It sounds like our users would have to get their own
 permission if they wish to redistribute.
