this is my solution to anyone with problems with manpages, or for anyone
that doesn't like "cat" pages taking up their disk space.  they use
MANPATH, so i deleted /usr/bin/manpath and /etc/manpath* and all my cat
pages.  it's just a quick hack, but i'm happy now!  i know there's a
million people that can do things better, this is just for the few dumber
than me! :)
