Basically, after I run rosdep, a macports process consumes 100% of my CPU and commands I enter in the terminal aren't displayed (stdin is stolen).  I have macports 2.0.3 and am using the ros-1.6.6 tagged version of ros.  Has anyone else had this problem?

There's a popen command which opens up a macports session, but the process doesn't look like it's being killed.  This would explain why I/O is being stolen, though I'm not sure why my CPU usage spikes.  My quick fix was to just change the command to be "port help" (see diff bellow).
