correct way to append to search directories for man

[Will Senn <will.senn%gmail.com@localhost>]

    I'm scratching my head
      trying to add a path to the manpath so that I don't lose the
      existing search directories:
      
    man -p
      
      /usr/share/man/man1
      
      /usr/X11R7/man/man1
      
      /usr/pkg/man/man1
      
      /usr/share/man/man8/amd64
      
      /usr/share/man/man8/x86
      
      /usr/share/man/man8
      
      /usr/pkg/man/man8
      
      /usr/share/man/man6
      
      /usr/pkg/man/man6
      
      /usr/share/man/man2
      
      /usr/share/man/man3
      
      /usr/X11R7/man/man3
      
      /usr/pkg/man/man3
      
      /usr/share/man/man3lua
      
      /usr/share/man/man4/x86
      
      /usr/share/man/man4
      
      /usr/X11R7/man/man4/x86
      
      /usr/X11R7/man/man4
      
      /usr/share/man/man5
      
      /usr/X11R7/man/man5
      
      /usr/pkg/man/man5
      
      /usr/share/man/man7
      
      /usr/X11R7/man/man7
      
      /usr/pkg/man/man7
      
      /usr/share/man/man3f
      
      /usr/share/man/man9/x86
      
      /usr/share/man/man9
      
      /usr/share/man/man9lua
      
    I just want to get /usr/local/share/man into the mix. I
    tried:
    export
      MANPATH=/usr/local/share/man:$MANPATH
      
    and various related incantations and all I wound up with was
    my directory being searched and not the others - which makes sense
    cuz MANPATH overrides the path... nevermind that this isn't how it
    works on linux or freebsd or...
    
    I also tried adding a section in /etc/man.conf where all those other
    directories come from:
    # Other sections
        that represent complete man subdirectories.
      
      X11R7           /usr/X11R7/man/
      
      packages        /usr/pkg/man/
      
      local           /usr/local/man/
      # mine
      share            /usr/local/share/man/
      
    No go. I tried running:
    makemandb -f
      
    in the hopes that the /etc/man.conf file didn't cause it to
    be picked up.
    
    I rebooted.
    
    No go. What do I need to do to get my directory added into the
    search directories?
    
    Thanks,
    
    Will
