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.
