Ticket to try to resolve what license crafty is under. What's the correct license in macports?

Debian has received written permission in the form of an e-mail from
Professor Hyatt:

On Thu 14. Mai 22:13:48 CEST 2009 autobuilding was requested 
by Oliver Korff <> of, 
this is the mail snippet:

I would like to request autobuilding crafty. The licence is strictly non-free, 
but we have the explicit written permission to redistribute of the upstream 

I have had contact with him recently and am convinced that the reason for 
making it non-free, is the code abuse in computer chess tournaments as 
mentioned in the copyright file.

We also do not alter craftys name or copyright notice, so everything that 
matters to the upstream author stays intact. Autobuilding does not interfere 
with that.

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.

r147093 I haven't bothered asking the author for an exception like Debian received.
