Next, switch your version specifiers from require to gem... whatever rubygems doco you read is old and require with a version specifier is deprecated: gem 'inline', '>= 3.6.6' Better... remove all version specifiers... there isn't anything across those versions that requires locking in the version. Follow that up with some cocoa.
