If this is an upstream issue, I'll file a bug ASAP but I need to be sure it's not related with gentoo.
@aballier found that upstream knows the issue https://github.com/ros-infrastructure/catkin_pkg/issues/97 and told the users to abide to the layout. There is something in the ros-catkin.eclass that is not compliant?
please reopen if this still fails with latest tools/ebuilds might have been an issue with our patches
