Hello.
I have Mac OS X Snow leopard that has pre-installed Ruby 1.8.7 and Rails 3.0.1 I need to work with Redmine a bit that requires Rails 2.3.5
Is it possible to correctly downgrade my current rails 3.0.1 to rails 2.3.5?

A:
You don't need to downgrade, RubyGems allow you to install multiple versions of the same library.
$ gem install rails -v 2.3.5

Is it any way to set a 'current version', so my rails commands refer to 2.3.5, not 3.0.1? (for example, rails -v shows 3.0.1 after installing 2.3.5)

No, you need to remove 3.0.1 or use `rails _2.3.5_ COMMAND` instead of `rails COMMAND`

`$ gem uninstall rails`, then select the version.
