[Vm-beginners] Generating CogVM

[Lars]

Hi,
with all the recent updates, I just compiled Cog again and it works like 
a charm (Thanks Eliot). Only when generating the sources, #ensureCR is 
called on a NullStream, which is not implemented yet. The patch is 
trivial, in that it is a method without (meaningful) return-value and no 
behavior.

Has anybody else had that problem? NullStream is from the package 
Collections-Streams, so patching that missing method would be their job? 
Or should we just add that method to the VMMaker.oscog-package?
Best,
Lars
