Look in config/environment.rb for a line like this, or add it if necessary:

# Specifies gem version of Rails to use when vendor/rails is not present RAILS_GEM_VERSION = '2.3.5' unless defined? RAILS_GEM_VERSION

Or as implied by the comment, freeze rails (AKA vendoring Rails). Google 'freeze Rails' for implementation details.

You should look at the gemsets feature of rvm. Then you can use the .rvmrc file in each project to select a gemset (and a ruby interpreter). After you've done this, each project will see just its own gems. You can use bundler to manage the gems locally, too, which makes it quite painless to deploy to the production environment for each project and get just the set of gems needed.
