Hi, I'm accessing the Amazon AWS API using the ruby-aaws gem, but without going to much into details of the API or the gem, I think my problem is more of a general nature. When I query the API I will end up with "object array", let's call it item, containing the API response. I can easily access the data in the array, e.g. puts item.it...

We have a ruby application that depends on a gem with native extensions (in this specific case Nokogiri). However, for various reasons we cannot install the build prerequisites (such as build-essential, libxslt-dev, ruby-dev, etc) for that gem onto our production host. Is there a (standard?) way to repackage the gem with the native exte...
