Hi Eric, But when I try to update a named gem, I get the new version, but also still have the old version (if I do gem list I can see both versions). So maybe I'm missing what you mean by "update" - looks to me like it simply installed the new one alongside the old one, no different than if I had done "gem install" to install the latest version. I'm currently on RubyGems 1.3.2. Thanks again, Jeff
