Rails - Jul 2009 - Could not find RubyGem rack (~> 1.0.0) (Gem::LoadError)

Here is some help for the folks just learning Rails

I am following the Sitepoint book by Patrick Lenz "Simply Rails 2"
and received an error message when attempting to run the command
"rails shovell"    to create a new rails application.
I got a load error.
Note:
remember to use a Ruby Console Window.
run the updates:
gem update
gem update --system
gem install rails
gem install Ruby


without installing rails you''ll get an error as shown below.
error shown here:

gem install rake?

however, it should have installed rake gem because rake gem is a 
dependency of rails, so...maybe "gem install rails" will get you the 
right version.
