How do you change Rails version on a mac?

I've got Snow Leopard with Rails 2.3.5 installed along with other versions (2.2.2 and 1.2.6). I'd like to use 2.2.2 as the webserver I want to deploy to uses a 2.2.x version of Rails. I've tried to uninstall Rails 2.3.5 but get this error:

ERROR:  While executing gem ... (Gem::InstallError)
    cannot uninstall, check `gem list -d rails`

Is there any other way of setting the Rails version to one of the other installed Rails versions?

You should be able to do this without needing to uninstall anything. You can specify the version of rails you want to create an application for by typing the following when creating a new app.

rails _2.2.2_ app_name
