PhantomJS version requirement not mentioned.
Was installing the Dev kit and ran rspec.
Now some test fail with this message;
Cliver::Dependency::VersionMismatch: Could not find an executable 'phantomjs' that matched the requirements '~> 1.8', '>= 1.8.1'. Found versions were {"/usr/bin/phantomjs"=>"2.0.0"}.
Please mention version restrains in the Install Guide.
