I was wondering what the appropriate workflow was for adding an additional package management system to an OS in rosdep.
Specifically, I was looking into building ROS on OS X Lion with Homebrew rather than macports. I figured out how to hard code it to use my version of InstallerAPI (HomebrewInstaller), but I am unclear on how you are supposed to select a which package system ROS will use on a given dependency. For example, if rosdep is trying to check for or install graphiz, how do I tell rosdep to use homebrew rather than macports?
Thanks in advance,
