Gem dependency conflict between coffee-rails and rspec-rails

Question

I'm upgrading an app from rails 3.1.1 to rails 3.2. I had to update version of coffee-rails as well as rspec-rails to their latest versions to work with rails 3.2. However, they both seem to be incompatible with each other. When I run the bunder I get

  In Gemfile:
coffee-rails (~> 3.2.2) ruby depends on
  actionpack (= 3.2.0) ruby

rspec-rails (~> 2.8.1) ruby depends on
  actionpack (3.0.0)

However, on rubygems for rspec-rails, it clearly specifies the dependency to be >= actionpack (3.0.0)

Has anybody faced this before?
