I need to do some development with Rails 0.14.3, and since I was stupid and didn't freeze the environment at that point, I'm wondering how I should go about it afterwards. I'm not even sure the rake tasks that old include the possibility of freezing version. There is no option in environment.rb to set Rails version either.
I'm thinking about two different approaches; either copy the specific gems manually to vendor/rails, or modify the require-statements in environment.rb to require_gem the exact needed version.
Which approach should I use?
