🚀 go-pugleaf

I am trying to build epoch 4.0 on a DecStation 5000/120 running Ultrix 4.2a.
The second time it builds temacs I get the following:

ld  -X  -o temacs pre-crt0.o /usr/lib/cmplrs/cc/crt0.o dispnew.o scroll.o xdisp.o window.o  term.o cm.o  emacs.o keyboard.o macros.o keymap.o sysdep.o  buffer.o filelock.o insdel.o marker.o  minibuf.o fileio.o dired.o filemode.o  cmds.o casefiddle.o indent.o search.o regex.o undo.o  alloc.o data.o doc.o editfns.o callint.o  eval.o fns.o print.o lread.o  abbrev.o syntax.o unexmips.o mocklisp.o bytecode.o  process.o callproc.o   doprnt.o termcap.o tparam.o lastfile.o alloca.o   -lc 
ld:
Undefined:
Vxterm
x_term_init
syms_of_xfns
*** Error code 1

Am I missing something?
