Look closely: The message 'menuComponent:' is not understood by objects
of the class 'StRootComponent'. This means that the definition of the
setter method is missing, not the definition of the instance variable.

Try defining the message by something like

	menuComponent: aComponent
		menuComponent := aComponent

or whatever makes sense in the tutorial's context.
