1.7.1

I patched the cloud_controller and restarted it. My dea.yaml is set up as:

runtimes:
  ruby18:
    executable: /home/deploy/.rvm/rubies/ruby-1.8.7-p334/bin/ruby
    version: 1.8.7
    version_flag: "-e 'puts RUBY_VERSION'"
    additional_checks: "-e 'puts RUBY_PATCHLEVEL >= 174'"
    environment:
  ruby19:
    executable: ruby
    version: 1.9.2
    version_flag: "-e 'puts RUBY_VERSION'"
    additional_checks: "-e 'puts RUBY_PATCHLEVEL >= 180'"
    environment:

If I push a new Rails app, it starts using /usr/bin/ruby1.8 still and if you specify --runtime=ruby19 it fails with:

Could not find rake-0.8.7 in any of the sources

If possible, would you be able to include a gist of the startup script generated for your rails app when staged with the ruby18 runtime? You can find this file on the dea at /var/vcap.local/dea/apps/<your app name>-<hash>/startup
