I am trying to install Event Machine on Ruby 2.0 under windows 7 but I get the following error 

Temporarily enhancing PATH to include DevKit...
Building native extensions.  This could take a while...
ERROR:  Error installing eventmachine:
        ERROR: Failed to build gem native extension.

I tried using gem install eventmachine --pre but that didn't help either
