Suddenly can't read man pages

[Matthew Saltzman]

What would cause some users (me and root, in particular, but not others)
to be suddenly unable to read any man page that isn't already in
/var/cache/man/?  Any other man page displays a blank screen with the
(END) prompt from less.  Happens in GNOME and on the console.

TIA.
