Hello people,
Added aws-s3 and ran bundle install and this one popped up
Gem::RemoteFetcher::FetchError: bad response Internal Server Error 500 (http://rubygems.org/gems/xml-simple-1.1.1.gem) An error occured while installing xml-simple (1.1.1), and Bundler cannot continue. Make sure that `gem install xml-simple -v '1.1.1'` succeeds before bundling.
Oops!
Some one call its developers and tell them to fix it!
