Can't use 'rails' command after installing using gem install

Question

I've installed rails using 'gem install rails', but when I try to create a new project, I get the error: The program 'rails' is currently not installed. You can install it by typing:

sudo apt-get install rails

There were no error messages when I ran 'gem install rails'. How come I cannot run rails commands?

When I do sudo apt-get install rails, it will install an older version of ruby, 1.8. I want the newest, so I do not want to install rails from apt-get.

Edit: Figured it out. Had to add PATH="${PATH}:/var/lib/gems/1.8/bin/" to .bashrc
