Compilation problem

Hello Garnet users!

I am tryin to compile Garnet in CMUCL 19b with new CLX that should
understand SSH properly, but now having troubles with compilation.
Experiencing error all the time.  The very first comlain is this:

Invalid number of arguments: 3
   [Condition of type KERNEL:SIMPLE-PROGRAM-ERROR]

Restarts:
  0: [CONTINUE] Return NIL from load of
#P"home:garnet/opal/opal-compiler".
  1:            Return NIL from load of "garnet-compiler.lisp".
  2: [ABORT   ] Return to Top-Level.

Debug  (type H for help)

(OPEN-CLX-DISPLAY 3 "localhost")[:EXTERNAL]
0] 

And after that all goes wrong.  Can someone let me know what am I doing
wrong?  I am working from SSH, and my display environment (set by ssh
presumably) is:

DISPLAY=localhost:12.0

I've tried to work with both xhost + and -.  Same result. The CLOS and
CLX have been loaded.

Cheers,
Roman
