I'm having difficulty trying to use MathMorphs (as described in Ch.10 of 
  Guzdial and Rose (the "Bluebook"?)); I've been trying under 3.4 final. 
  MorphicWrappers installs fine, either from SqueakMap or the mathMorphs 
site linked from the Swiki.  However, ...

(a) support for linear algebra through morphic wrappers is provided 
through a second changeset (MatrixMorphicWrappers).  Two of the classes 
defined in the latter subtype a third class called SimpleMorphicWrapper, 
which I haven't been able to find in the various versions of the 
"wrapper" change sets I've tried.

(b) the Vertex class in the graph package on the mathMorphs site uses a 
class called "QuickPrint" which doesn't seem to exist in the current 
image (and about which the only hint I can find on the Swiki is an aside 
about "DisplayScanner's #quickPrint: variants").

Does anyone have these mathMorph classes installed and working, and if 
so, what combination of image, change sets, and/or packages should I be 
trying?

thanks,
David
