How to add Mac-specific gems to bundle on Mac but not on Linux?

Question

I\'m developing a Rails app on a Mac, and I\'m new to testing, so I just added these gems to my Gemfile:

group :test, :development do
  gem

@zed_0xff: found a similar approach in an older rspec-core commit:

if RUBY_PLATFORM =~ /darwin/
  gem 'foo'
end
