I am having a problem getting an old Ruby on Rails 2 app that hasn’t worked in a year to work.

I’m trying to run rake test:functionals in the root of my project directory, but am getting undefined method 'name' for "SystemTimer":String.

I’ve pasted everything that I believe relevant to the problem here:
http://pastebin.com/NgBvystZ

Also, when I run rake itself, I get
Errors running test:units!
Not sure how to debug that.

I have copied and pasted everything that I think would be useful to understanding this problem. Your time is greatly appreciated. Thank you.

    This is an incompatibility between versions of RubyGems greater than 1.3.7 and versions of Rails less than 2.3.12. There are a few ways to solve this.

    1. Use Bundler

      Bundler is easy to install, fixes this problem, and has a number of other advantages as well. I highly recommend it.

    2. Upgrade to Rails 2.3.12 or higher

      Rails 2.3.12 fixed compatibility issues with RubyGems 1.8.5 (see release report).

    3. Downgrade to RubyGems 1.3.7

      I would not recommended this unless you have no other choice. Use this command: gem update --system 1.3.7. Also, version 1.7.2 has partial compatibility (it will run, but freezing gems will fail and there are likely other issues).
