       Post-install message from rdoc:
       Depending on your version of ruby, you may need to install ruby rdoc/ri data:
       <= 1.8.6 : unsupported
       = 1.8.7 : gem install rdoc-data; rdoc-data --install
       = 1.9.1 : gem install rdoc-data; rdoc-data --install
       >= 1.9.2 : nothing to do! Yay!
       Post-install message from newrelic_rpm:
       # New Relic Ruby Agent Release Notes #
       ## v3.5.8 ##
       * Key Transactions
       The Ruby agent now supports Key Transactions! Check out more details on the
       feature at https://newrelic.com/docs/site/key-transactions
       * Ruby 2.0
       The Ruby agent is compatible with Ruby 2.0.0 which was just released.
       * Improved Sinatra instrumentation
       Several cases around the use of conditions and pass in Sinatra are now
       better supported by the Ruby agent. Thanks Konstantin for the help!
       * Outbound HTTP headers
       Adds a 'X-NewRelic-ID' header to outbound Net::HTTP requests. This change
       helps improve the correlation of performance between services in a service-
       oriented architecture for a forthcoming feature. In the meantime, to disable
       the header, set this in your newrelic.yml:
       cross_application_tracer:
       enabled: false
       * Automatically detect Resque dispatcher
       The agent does better auto-detection for the Resque worker process.
       This should reduce the need to set NEW_RELIC_DISPATCHER=resque directly.
       See https://github.com/newrelic/rpm/blob/master/CHANGELOG for a full list of
       changes.
       Post-install message from twitter-bootstrap-rails:
       Important: You may need to add a javascript runtime to your Gemfile in order for bootstrap's LESS files to compile to CSS.
