I hadn't updated my XFree86 4.x binaries in a very long time, so I
decided to cvs update the directory (xsrc/xfree), then did:

   make World
   make install

The make world seemed to complete with no errors, but when I did make
install, it got partway through, then exited with this:

  making all in programs/Xserver//drive2/src/xsrc/xfree/xc/programs/Xserver/hw/xfree86...
  make: don't know how to make XFree86.man. Stop

  make: stopped in /drive2/src/xsrc/xfree/xc/programs/Xserver/hw/xfree86
  *** Error code 2

Does anyone have an idea where this might have come from, or should I
just erase my work area and do a fresh cvs co?
