As to loading this (a fairly new project) into older versions of squeak, there may well be problems. Since squeak is constantly moving forward, the simplest assumption is that people will be using somewhat current versions and projects are published for those versions. I was able to load it in squeak 3.2 with no problems:
I was able to load this once, but the second time failed (I'd restarted Squeak cleanly in between, of course).
Part of the project loaded, but then I was presented with a dialog that said:
Trouble resolving server name "LearningMorphic.013". Keep trying?
And then I got a large number of MNU errors from processMouseOver: (leftMorphs was nil).

It seems like it's broken in some way w/r/t loading, and the UI is also broken during program loading.
