Rails 3.0.1 and Rake

I'm running Rails 3.0.1 and Rake 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-
WARNING: Global access to Rake DSL methods is deprecated. Please
    ... Rake::DSL into classes and modules which use the Rake DSL
WARNING: DSL method Vu::Application#task called at /home/ed/.rvm/gems/

Do I need a new version of something?

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

did that still getting it
