Hi all.
I've been experiencing a slight problem with rosdep and macports. 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?
Looking at the source, the issue seems to be a check for whether or not macports exists in the constructor of rosdep.installers.MacportsInstaller. 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).
Should I file a bug report?
Cheers,
Ben
