Couple questions:

  • what version of Rubygems do you have? The ‘bulk update’ message
    hints that it might not be the most recent, needed by 2.3.2.

  • something is seriously wrong with your rubygems install; the Rails
    gem shouldn’t be pulling down things like Camping and Markaby.

You’re not crazy. It’s broken.
cured by:
gem update --system

These instructions work great:

Thanks to Matt J. for the diagnosis.
