-----------------------------+--------------------------------
 I have macport's version of sudo installed on my 10.8 system. When I use
 it to run as root it works fine, when I try to run as a different user
 (macports), it would fail. I use the default configuration as provided by
 the port and see no obvious configuration issue.
