Stephan,
Can you take this to answers.ros.org? And in that question there can you
tell us what version of ROS you are using?
I do not get the same behavior as you:
∫ rospack depends geometry_msgs
> cpp_common
> rostime
> roscpp_traits
> roscpp_serialization
> genmsg
> genpy
> message_runtime
> std_msgs
--
P.S. in the future please follow the getting help guidelines:
http://ros.org/wiki/Support
Thanks,
