A comparision with Squeak 3.4 reveals that
Subdivision>>constraintOutline: was changed on 3/7/2003 by ar
(which is Andreas Raab).
The new version answers an Array and that array does not
understand build3DObject.
You can simple remove the statement
^outpoints contents in the method I mentioned.
The method will then answer the receiver (an instance
of PoohSubdivision in your situation) and that betters
the situation. I am however not convinced that this
is a valid fix.
