I'm familiar with Rails 3, but not rails 2. I've just inherited a rails 2 project with no Gemfile, but a bunch of config.gem lines in config/environment.rb
I'm just wondering how I to install these. bundle install returns Could not locate Gemfile.

The Gemfile is where you specify which gems you want to use, and lets you specify which versions. The Gemfile. lock file is where Bundler records the exact versions that were installed. This way, when the same library/project is loaded on another machine, running bundle install will look at the Gemfile.
A Gemfile. lock is auto-generated & it says exactly what versions of every gem were installed. Bundler will install these versions so when you deploy this application to production, or share your project with other developers, everyone will be working with an identical set of gems.
Select Tools | Bundler | Install from the main menu. Open the Gemfile, place the caret at any highlighted gem missing in the project SDK and press Alt+Enter . Select Install missing gems using 'bundler' and press Enter .
run the command bundle install in your shell, once you have your Gemfile created. This command will look your Gemfile and install the relevant Gems on the indicated versions. The Gemfiles are installed because in your Gemfile you are pointing out the source where the gems can be downloaded from.
You can install gems in rails 2.x by using the rake command
rake gems:install
