I filed a bug on launchpad about this package being missing:
https://bugs.launchpad.net/precise-backports/+bug/1056203. It will
probably be picked up in the precise-backports soon, is it ok for ros
debians to depend on this extra repository? Can the debuild system
handle this? ATM this package is only available in my private ppa:
https://launchpad.net/~smits-ruben/+archive/ppa.

What is the position of ROS wrt this situation?
