You still have to be able to handle MANPATH.  Unfortunately the man page
of man-db is a little tight-lipped on how MANPATH is handled exactly,
other than that "its value is used as the path to search  for manual
pages."

Whatever man does with MANPATH, it doesn't drop the default man paths,
apparently.

[...time passes...]

Hmm.  Interesting enough, the current /etc/man.conf already contains
/usr/ssl/man.  How long is it doing that already?  If I had known that,
I'd removed the /etc/profile.d/openssl.* files long ago :|
