Not sure I'm kinda noob ;-) I was reading FAQ and found out tha there is a stable ports tree in that strange looking table:
http://openbsd.org/faq/faq15.html#PortsFetch
So I entered
% cd /usr; cvs checkout -P -rOPENBSD_4_3 src
and it downloaded something ;-) Maybe it is current... Don't know. It says patch branch. Anyway maybe I'm wrong but they should update those docs more often ;-)
PS. When they decided to discontinue it?
PPS. Sorry for offtopic.
