I just setup ruby and was trying to run the following commands:

> > class Story \< ActiveRecord::Base; end  
> > =\> nil
> 
> > story = Story.new

From what I read it said that there might be problem with /etc/hosts  
I checked it and what I have in there is:

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost localhost

Have you checked your config/database.yml ?? try to restart your console  
and open new cmd or shell then start again your console. If still error  
try to update your Gem Active Record.
