You should run_depend on it.

This is what I would do:

   1. clone your release repo manually and go into that directory
   2. run `git-bloom-release groovy` (only if you haven't run it for this
   version)
   3. change to the branch you want to patch `git checkout
   debian/groovy/youbot_driver`
   4. Make your changes and commit `git add . && git commit -am "some
   message"`
   5. Export the patches `git-bloom-patch export` (shouldn't be required,
   just to be safe)
   6. I like to go back to master `git checkout master` (shouldn't be
   required)
   7. run the bloom release again `git-bloom-release groovy` (this makes
   your changes propagate to the leaf tags which the build farm uses)
   8. Go to the resulting tag `git checkout
   debian/ros-groovy-youbot-driver_0.1.3-1_precise` (something like that)
   9. Build the deb `git-buildpackage -uc -us`
   10. Test it `cd .. && dpkg -i *.deb`

Some of those commands might need tweaking as I just listed them off the
top of my head.
