Rails 3.0.1 and Rake

I'm running Rails 3.0.1 and Rake 0.9.2.2 and when I run Rake I get
these warnings:

WARNING: 'require 'rake/rdoctask'' is deprecated. Please use 'require
'rdoc/task' (in RDoc 2.4.2+)' instead.
    at /home/ed/.rvm/gems/ruby-1.9.3-p0/gems/rake-0.9.2.2/lib/rake/
rdoctask.rb
WARNING: Global access to Rake DSL methods is deprecated. Please
include
    ... Rake::DSL into classes and modules which use the Rake DSL
methods.

ruby-1.9.3-p0/gems/railties-3.0.1/lib/rails/application.rb:214:in

Do I need a new version of something?

Add this lines to your Gemfile and run bundle
  gem 'rake', '~> 0.9.2.2'
  gem "rdoc", '~> 3.12'

did that still getting it
