I just attempted to do an update from #4411 in an mvc project and got:-
 18 December 2001 4:30:29 pm
MessageNotUnderstood: currentNaturalLanguage

VM: RiscOS - Squeak3.1alpha of 7 March 2001 [latest update: #4164]
Image: Squeak3.1beta [latest update: #4420]

UndefinedObject(Object)>>doesNotUnderstand:
EToyVocabulary(ObjectWithDocumentation)>>translatedToPrevailingLanguage
EToyVocabulary(ObjectWithDocumentation)>>wording
EToyVocabulary(ObjectWithDocumentation)>>documentation:
EToyVocabulary>>initialize
EToyVocabulary class(ObjectWithDocumentation class)>>new
Vocabulary class>>addEToyVocabulary
Vocabulary class>>changeMadeToViewerAdditions
UndefinedObject>>DoIt
Compiler>>evaluate:in:to:notifying:ifFail:

... which seems to be due to translatedToPrevailingLanguage refering to
ActiveHand. ActiveHand is nil in an mvc project.
