FYI, finally got it working after a week of struggle:

Just use "pecl install xdebug" at the command line!

 ... the wizard just doesn't work for me. I thought since I'm not a Linux/Admin guru the wizard would be the easiest ... but the above command did the trick.

I'm glad it works! Closing out this issue.
