You need to use the edge version of Spree with Rails 3.1. Add this to your Gemfile:

gem 'spree', :git => 'git://github.com/spree/spree.git'

Also, I think edge Spree is only compatible with one of the latest Rails 3.1.1 release candidates. You may need to add this to your Gemfile as well:

gem 'rails', :git => 'git://github.com/rails/rails.git', :tag => "v3.1.1.rc1"
