To install Vestal Versions, after adding the gem you have to run: "script/generate vestal_versions" not sure if that's a Rails 3 command so I tried: "rails generate vestal_versions" which gave "Could not find generator vestal_versions"
I did check to make sure it was installed: $ bundle show vestal_versions /Users/me/Sites/cline/vestal_versions/ruby/1.8/gems/ vestal_versions-1.0.2 Any ideas on how to install Vestal Versions? thxs again!
