Environment Hooks issue

[Terry Farnham]

I am successfully building and running my custom image that includes ROS.  I am, however, having an issue with the environment hooks that get included in the image.  Specifically, opt/ros/indigo/etc/catkin/profile.d/10.ros.sh attempts to call python using a path that exists on my host development system and not the one that exists on the target hardware.  Ideally, I could supply a bbappend file or some other post processing hook to the image generation in order to modify these errant paths, but I'm not exactly sure how these files get generated to begin with.  I'm hoping someone might have some helpful advice on how I can modify these files during the image build process.
