Fixing VNC port(s) for AMD64

Recent VNC distributions are shipped without X11 source.  Our VNC
port uses XFree 4.3 as that is the most compatible with the patch
provided in the VNC distribution, but the patch is trivial to fix
so it builds against a newer XFree or Xorg distribution.  The tough
part is getting a properly patched Xorg source tree for the port -
something each Xserver like port shouldn't have to replicate.
