openssh 3.5p1:
AF_INET6 is not included on FreeBSD 2.2.8

so skip it when not detected:

This should already be taken care of by the openbsd-compat/fake-socket.h header.
What is the error that you get during compilation?

Looking closer, I mixed this up, its in openss-3.5, not in openssh-3.5p1!
testing again my fix is not needed in the püortable version.
