DevTool/bin/instlserver: No such file or directory

When building ls.mac, I get to the very end, and then this message comes
out:
lserver.lnk fast
!$TOOL/bin/instlserver
/bin/sh: /home/mark/DevTool/bin/instlserver: No such file or directory
COMMAND error 127
'ls.mac' not made because of dependency errors
24-01-03 19:29:58 end    of    ls.mac   fast


There is no file by that name, anywhere on the system that I can see.  The
instructions on the web site say to do this:
         4.Execute the following commands as user root.
          chown root <...>/DevTool/bin/instdbmsrv
          chmod 4775 <...>/DevTool/bin/instdbmsrv
          chown root <...>/DevTool/bin/instlserver
          chmod 4775 <...>/DevTool/bin/instlserver
but the files don't seem to be getting built by the "make" command.  Where
are these files supposed to come from?
