Error when installing json gem for ruby 2.0-Collection of common programming errors

I’m running ruby 2.0.0p0 on Mac OSX 10.9 and trying to installing the gem json but keep getting an error message that it has failed to build the gem native extension.
I attempted to update the rubygems with: gem update –system but still get the same error message.
Do I need to possibly install a different version of json (other than 1.8.1) for the version of ruby I am running?
Here is the full output in case that helps to see the issue:
Building native extensions.  This could take a while...
ERROR:  Error installing json:
    ERROR: Failed to build gem native extension.
