Answer 1

Suggest using bundler to manage the gems in your project.

If you put

 source 'http://rubygems.org'

 gem 'rails', '3.0.9'

in your Gemfile (see also http://gembundler.com/ )

Then

 bundle install

will install the correct version of rails and

 bundle exec rails console 

will start up your console. bundle exec rails server will start the server, etc.

You might also want to consider using rvm to install and manage your rubies if you aren’t already — http://beginrescueend.com/
