Hi (tl;dr: latest aws gem v.2.5.2 and ruby v.1.8.6 == problem)
I ran into an issue using the EC2 driver today - it is particular to ruby 1.8.6 (yes i really need to get off fedora 13...) and the latest aws gem v. 2.5.2. Basically aws gem uses "string.each_char" which doesn't exist in ruby 1.8.6 (introduced in 1.8.7). I requested a minor fix using "string".to_a.each (aws github pull request https://github.com/appoxy/aws/pull/89 ) - don't know if appoxy aws folk are interested in maintaining 1.8.6 compatibility though,
