Thanks for the options.

I tried using the --checkout-ww command. It pulled down a complete copy of
the core BUT the PartsBin folder only contained a single folder called zp,
which was empty.

I did a lk partsbin, and that seemed to bring down the full partsbin.
However, looking at the error messages, it seems as though the core - as
installed by the osx app doesn't include much in the apps directory.  I am
currently shuffling things around to try to get one complete image.
