a: following ubuntu based source install on http://www.ros.org/wiki/groovy/Installation/Source

** install ros/groovy on debian

running catkinmakeisolated

1. opencv2 is always remade
2. /home/x75/roscatkinws/installisolated/lib/libimagetransport.so is missing in polledcamera $ vim CMakeFiles/polledcamera.dir/link.txt
3. pcl segfaults with parallel make (e.g. -j2), do standalone make in build dir, then rerun catkin

rosmake -a
