Description of problem:
(rails new  ... --skip-bundle) fails.  (I haven't let a non---skip-bundle run finish; that would defeat the point of using RPMs at all.)

Additional info:
This is not the only possible failure mode; the above is after a manual installation of at least rubygem-coffee-rails, perhaps other gems as well.
