I just upgraded to Linux Mint 14 and to Rails 3.2.9 from 3.2.8. Now I'm getting this error when I run rake db:create

rake aborted!
undefined method `values_at' for "MySQL.  Versions 4.1 and 5.0 are recommended.":String
Tasks: TOP => db:create

my Gemfile looks like this:

source 'https://rubygems.org'

gem 'rails', '3.2.9'
gem 'execjs'
gem 'therubyracer'

# Bundle edge Rails instead:

gem 'mysql2'

# Gems used only for assets and not required
# in production environments by default.
group :assets do
  gem 'sass-rails',   '~> 3.2.3'
  gem 'coffee-rails', '~> 3.2.1'

  # See https://github.com/sstephenson/execjs#readme for more supported runtimes
  # gem 'therubyracer', :platforms => :ruby

  gem 'uglifier', '>= 1.0.3'

gem 'jquery-rails'

Is it possible that you forgot to update some dependencies? Try to run:

$ bundle outdated

and check if you need to update other gems....
