Get scaffold running on host.  See details...

Passenger is unable to find gems if they are located in two different folders.  Installing any new gems (or triggering any upgrades) will install the gems locally.  Passenger is unable to find these gems.  Installing them all in cache/vendor is not an option, because some of them won't build.

Solution: Lock each gem version to the one that's already installed on the host.

$: gem q L > gems.txt  ## gem query List

then search through gems.  Once locked, it works.

Development.rb copied to production.rb short-term, cause it's late and I'm really tired.
