Accodrding to [Ruby on Rails — A web-app framework that includes everything needed to create database-backed web applications according to the Model-View-Controller (MVC) pattern.](http://www.rubyonrails.org/down:)  
1.I run following:  
gem install rails --include-dependencies  
ERROR: While executing gem … (RuntimeError)  
Error instaling rails:  
rails requires rake \>= 0.7.2  
Don’t know how come and where can I find the “rake”.

2.Later re-run:  
gem install rails --include-dependencies  
ERROR: While executing gem … (Gem::RemoteSourceException)  
HTTP Response 407  
Why HTTP?

3.I downloaded:  
rails-1.2.3.gem and rails-1.2.2.tgz, how to use them?

How come there is no complete doc?  
How come so many seperated packages?

the cause of these errors is most likely to do with ruby/gems  
try removing and reinstalling these items

then run the command line again
