Problems installing Rails

Hi,

 I'm trying to install rails in my desktop and the command "gem

install rails --include-dependencies" shows the following message:

INFO: gem install -y is now default and will be removed
INFO: use --ignore-dependencies to install only the gems you list
Successfully installed rails-2.0.1
1 gem installed

I think the dependencies were not installed, because in my

notebook it doesn’t happened.

Is it happen with someone?
What can I do to install all the dependencies?

Thanks,
Osiro
