Minitest is installed:

Yanniss-MacBook:rechnungen yannis$ gem list minitest

*** LOCAL GEMS ***

minitest (2.6.1)

And Google doesn't return anything... I need your help...

Thanks a lot, Tom

I fixed this by applying a Pessimistic Version Constraint to turn in my Gemfile:

group :test do
  gem 'turn', '< 0.8.3'
end

Update: The version constraint should no longer be necessary, according to a maintainer:

Technically .. MiniTest is an optional dependency .. It would not normally be an issue .. but the MiniTest shipped with Ruby is well behind the latest version of MiniTest, which Turn needs. Since almost everyone has moved to MiniTest now, I will simply add it as a dependency.

I haven't verified the above because I use rspec now.
