Compiling Viewmol

         I am trying to compile the source for Viewmol 2.1 and am having
 trouble with link step.  The error I am getting is:
         /bin/sh getmachine viewmol

 I am using IRIX 4600/5.3.  Any suggestions would be appreciated.

 "Scepticism is the chastity of the intellect, and it is shameful to
 surrender it too soon or to the first comer:  there is nobility in
 preserving it cooly and proudly through long youth, until at last,
 in the ripeness of instinct and discretion, it can be safely exchanged
 for fidelity and happiness."			George Santayana
