I am trying to install ruby debug 19 so I can run spork. I am getting errors though that are very frustrating. I've googled for a while to no avail. I am running 1.9.3-p194.
Here's the error message:
Building native extensions. This could take a while... ERROR: Error installing ruby-debug19: ERROR: Failed to build gem native extension.
