4105 monitor troubles

Netters:

     I'm trying to gmake4.0 the tek 4105 monitor driver on an HP under
System V, but I can't get past this:

  CMD = /usr2/grass/grass4.0/src/CMD
  HEADER = grass.hnw
  ARCH = hp
  GISBASE = /usr2/grass/grass4.0/hp

Stop.

     Can you make any helpful suggestions? I get a very similar error on a
SUN Sparc 2+.
                           Thanks for your consideration,
