Hi William, Thanks for the infos, but that's actually not the point. In fact I can install ros-groovy-perception-pcl and it's dependencies without problems on my Debian sid using Ubuntu as an extra repository. The problem is, that the PCL version in ROS is not integrated into the filesystem and the package is not split into lib, bin and dev packages, meaning that I need to change my installed boost development version for example. Next the dependencies are wrong, so the package depends on libboost1.46-all-dev instead of the specific libs, so I guess dh_shlibdeps, which would automatically add the right dependencies, is disabled. If you want to see how it could be done, have a look into the Debian dir from my PPA version (note that I'm not an official Debian developer, so I can't give final answers here). Sorry for hammering on this, but I would really like to see ROS in Debian and Jack you are absolutely right, I should join the list, only that I don't want to get involved into that to much because of time constraints ;). Cheers Jochen
