OpenBSD did miminal changes to FreeBSD's bsd.port.mk (look at the name
in the latest rev for who integrated it :-).  I have a firm commitment
from key FreeBSD folks to allow OpenBSD/NetBSD patches to the ports
into the tree.  Send me patches, and I'll commit them to the tree
after the usual review process :-).

OpenBSD uses the raw FreeBSD tree...
