Thanks Marcus, for trying this. I tried what you suggested and there was
no love. I even tried to uninstall, then rm'ed the build folder and
rebuilt, with still no luck. You cloned the "syncing" branch, right? The
"master" branch works fine. I have gone back a couple of times to see if
I could figure out what I broke.
