I would go back and work through from the beginning, installing the version of Ruby the tutorial advises using RVM. This will make it MUCH easier to learn.
OR
If you feel confident, and are up to the challenge, you could skip forward to the last chapter, get an understanding for the differences and changes you need to make in order to get the application working in 3.1. Then work through it from the start, making changes for 3.1 as you go. BUT, this would potentially be very confusing and frustrating for someone just learning frameworks and programming for the first time.
I chose the first option. I found this gave me a greater understanding of Rails, as I now understand how 3.0 worked, but have since moved on to working with 3.1
As covered in another comment, don't be fooled in the small version number. They made some very significant changes to 3.1 that change the way you work with Rails completely.
Good luck, followed from the start, this is a excellent tutorial.
