rake doesn't


I'm a novice user trying to follow the Getting Started Guide on a OS X machine. To set up the database I need to use the command:

rake db:create

It comes back with:

rake aborted! no such file to load -- bundler/setup

(See full trace by running task with --trace)

Using --trace reveals that rake:

/Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 78:in `load_rakefile' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 129:in `standard_exception_handling' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 77:in `load_rakefile' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 61:in `run' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 129:in `standard_exception_handling' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/lib/rake/application.rb: 59:in `run' /Users/willem/.gem/ruby/1.8/gems/rake-0.9.2/bin/rake:32 /usr/bin/rake:19:in `load' /usr/bin/rake:19

I'm out of my depths here. Could anyone please help me get over this hurdle?
