I'm having problems with my ruby on rails application running on bitnami cloud with a Amazon EC2 instance. It seems it doesn't install any gems. I'm using bundler gem, but when I try: bundle update I've a HTTPError. When I get apache log error I see: "undefined local variable or method `handles_sortable_columns' for ModemsController:Class" It seems handles_sortable_columns gem is not installed Any help?
