Ruby DevKit on Windows 8, still can't install native extension

I'm using Ruby 1.9.3 on Windows8-64bit. My Ruby installation is in C:\Ruby193 and the Devkit is in C:\DevKit

I followed the DevKit installation and it's a success.

Then the guide asks me to test it by running gem install json --platform=ruby which returns this error (looks similar as before having DevKit installed):

Note: This other question here told me to add the DevKit installation folder to Environment PATH, I did it but still got same error.

C:\Users\myname>gem install json --platform=ruby
Building native extensions.  This could take a while...
ERROR:  Error installing json:

Any solution? Thanks

Sorry, I used the wrong DevKit.

For Ruby 1.9.3 and below, we should use DevKit-tdm-32-4.5.2-20111229-1559-sfx.exe The mingw is for 2.0 and above.

It works great now.
