Is Windows 64 a supported platform? During the installation it fails to compile with this error (Ruby 2.0.0-p195 installed via RubyInstaller):

>gem install oj -v 2.1.0
Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing oj:
