Mickey advised me on IRC that the OM core team does indeed want external
developers to use that frozen OE version.

I have updated MokoMakefile to use that frozen version.  It will also
detect if you have a different checkout (all existing users will be in
that situatin), and ask you to either clobber and rebuild, or to
unfreeze the OE version to continue with your current checkout.

Note that if you continue with your current unfrozen checkout, you will
not be building the same images as the OM core team is building.

So everyone is strongly encouraged to clobber and rebuild as directed by
the message that MokoMakefile will print out for you.

Go and enjoy Easter with your family as it rebuilds :-)
