Rails

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.
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
