On a clean Rails 4 install with Bundler 1.3.0, using --binstubs causes competition between Rails and Bundler for the contents of bin/rails (and bin/rake).

Just running bundle will rewrite the Rails version of bin/rails to a version that doesn't work.

The fix is to use the new bundle binstubs <gemname> command.

(see rails/rails#8974)
