Rails - Apr 2006 - error with database.yml when running rails generate script

Hi All,

I''m learn about ruby and rails in the same time.
I got error when running rails generate script when trying to create
application with db

It give me error like this
"/usr/local/lib/ruby/1.8/yaml.rb:133:in `load'': syntax error on
line
33, col 8: `  #host: localhost'' (ArgumentError)
        from /usr/local/lib/ruby/1.8/yaml.rb:133:in `load''
        from
/usr/local/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/initializer.rb:424:in
`database_configuration''
        from
