This kind of initial errors is quite common but of course not welcome.
I have just solved some of them. So if you will see that, you may try
to find a solution. One iffy problem is with the LRUCache.

I looked at it and "SMSqueakMap bootStrap" solves it but we have to
find a better solution.

Great, what about MinimalMoprhic system?

There's very simple test how to see the overrides. Firstly you have to
evaluate this code:

| sources  |
sources := Dictionary new.
Smalltalk allClassesAndTraits do: [:c |
       | methods |
       methods := sources at: c name put: Dictionary new.
       c selectors do: [:sel |
               methods at: sel put: {(c sourceCodeAt: sel) asString. c
organization categoryOfElement: sel} ].
       c isTrait ifFalse: [
               methods := sources at: c class name put: Dictionary new.
               c class selectors do: [:sel |
                       methods at: sel put: {(c class sourceCodeAt:
sel) asString. c class organization categoryOfElement: sel} ]]].

Smalltalk at: #OldSources put: sources.


then load the package, open transcript and evaluate this one:


OldSources keysAndValuesDo: [:class :methods |
       methods keysAndValuesDo: [:sel :source |
		| newSource newCategory |
		newSource := ((Compiler evaluate: class) sourceCodeAt: sel) asString.
		newCategory := (Compiler evaluate: class) organization categoryOfElement: sel.
		((newSource = source first) and: [newCategory = source second]) ifFalse: [
			Transcript show: class; show: ' >> ', sel; cr ]]].


this is list of overrides of MinimalMorphic: http://www.comtalk.net/Squeak/102
