If you update at the moment, when you get to loading Morphic-fbs.663
you'll get a walkback because in Class >> #declare:,
PianoRollNoteMorph's environment instvar is nil.

Which is kind've odd. I thought that all classes MUST have an
environment (and that right now that environment is Smalltalk).

So I've tried moving Sound and Morphic (the source & destination
packages for the PianoRollNoteMorph move) around in config maps, and
that doesn't help.

What gives? How can I fix this?
