Why is rails installing a newer version when I run bundle?

I am trying to start a new rails project and I would like to stick with rails 3.1.3. However, when I run the command rails new projectname I get the following output:

  create  
  create  README.rdoc
  create  Rakefile
  create  config.ru
  create  .gitignore
  create  Gemfile
  create  app
  ...
  create  config
  ...
  create  config/database.yml
  create  db
  ...
  create  public/robots.txt
  create  script
  create  script/rails
  create  test/fixtures
  create  test/fixtures/.gitkeep
  ...
  create  tmp/cache
  create  tmp/cache/assets
  create  vendor/assets/javascripts
  ...
  create  vendor/plugins/.gitkeep
     run  bundle install

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.

I'd like everything to remain version 3.1. Why does the rails command automatically update itself to 3.2.0.rc2? How can I make sure that everything I do is using 3.1.3 versions of everything?

Thanks.

It is relatively little known fact that you can specify the rails version for a new application _like.this_

rails _3.1.3_ projectname

will work assuming 3.1.3 is installed (gem install rails -v3.1.3 otherwise)

This also works with rails 2 apps, i.e. pre-bundler and will create a rails2 looking application in these cases, e.g. rails _2.3.8_ projectname Again gem install rails -v2.3.8 if necessary (i.e. first time usage on that machine).

Longer term make sure you are using rvm (now a defacto standard) and you can use that toset your default rails (as well as ruby).

Removing the old version can be done with sudo gem uninstall rails -v 3.2.0.rc2
