Sorry for the self-followup, but I also don't have a '/usr/lib/private'
*at all*, despite the fact that I upgraded to 9.3 from 9.2 using
freebsd-update. I also don't seem to have some other things mentioned
(for example, my OpenSSH is version 6.2p2).

So it would seem that maybe I missed a post-reboot install step on one of my previous
upgrades (though I thought freebsd-update was supposed to figure that
out and resolve it if it managed to happen).

If that's the case, what's the safest way using binary updates to get my
system to where it should be, rather than to where it thinks it is?
Should I just get the 'base' tarball, or is there a better way?
