default location for xauth in sshd_config has changed
This changed in version 3.4 and 3.5. I tried to ssh with X forwarding both to my old box darner after upgrading kernel and world, and to zyxomma with a fresh 3.4 install. ssh -v showed that it did not find xauth. A commented-out line in sshd_config implies that the default is /usr/pkg/bin/xauth, which is where xauth is. I uncommented the line, restarted sshd, and successfully got an ssh connection with X forwarding.

What do you perceive to be the problem? It's not clear.
That the xauth line is commented out and should not be?
Assuming that's your suggested action, what do you do about the folks using dports instead of pkgsrc, who would need a path of "/usr/local/bin/xauth" ?
