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).

Yes, please use the bug tracker to file patches instead of ros-users.
It's easier to track and follow up on.

There is a link to create new tickets at the bottom of the rosdep wiki page:
