The current autoproj version fails (Ubuntu 16.04, rock had been installed on the machine before):

Workaround: Changing into an existing rock installation and running aup solved the problem, probably by updating the autobuild gem? Anyhow, afterwards a clean reinstall of rock doesn't throw the above error.

Whoops, false alarm. Turns out I had made a local modification to that file, and this modification crashed with an empty CMAKE_PREFIX_PATH.

Sorry about the noise.
