This is not a common piece of cargo that Unix newcomers acquire;
historically, I suppose a lot of man(1) implementations didn't support
$MANPATH, but man-db has for decades, and I see mandoc(1) does too.

FWIW, with man-db, it's usually best for most people not to set MANPATH 
at all unless manual pages are somewhere that can't be straightforwardly 
derived from PATH.  man-db will normally work it out based on PATH, and 
that way it's harder for them to get out of sync.
