When adding Pony to an existing project I got a 'Debugger failed' message. I had this working in other projects so I was a bit surprised. In any case after looking into it I noticed there is error info so that should be outputted as well to help the user diagnose the issue.
Make 'Debugger failed' message more informative.
Now gives users more info to act upon when they get the debugger failed message
Sounds fair. Thanks for the contribution.
