gnut now works on OpenBSD

[rob <europax@home.com>]

Don't know if anyone else is interested in Gnutella, but I now have a
working gnut for OpenBSD.  I worked with the software author who made
some changes.  The current version is 0.4.16.  I think the next version
will have the changes, since this new version works on Linux as well.  

I have binaries, but I barely a clue on how to turn this into a port.  I
want to learn so I can do more of this, and give something back (other
than CD and T-shirt orders :) 

One major question-  I originally couldn't get gnut to compile since it
was looking for /usr/include/readline/history.h.  I took that file out
of my source tree and put it into that directory. Then it compiled.  How
does one deal with that in a port?  

Thanks,  Rob.
