Hi Radu,

Many thanks for the clarification.  I wanted to try out openni_pcl and I 
was starting by trying to install the main ni stack by following the 
instructions at:

http://www.ros.org/wiki/ni

These worked fine on another machine early this morning but now I am on 
a different machine with a fresh install of Ubuntu 10.04 and the latest 
C-Turtle debian packages and I get the following failure messages after 
executing the last step (rosmake ni)

\[ rosmake ] Expanded args ['ni'] to:
['openni', 'nite', 'openni_tracker', 'ps_engine', 'openni_camera', 
'pointcloud_to_laserscan', 'disparity_view', 'openni_pcl']
[ rosmake ] Checking rosdeps compliance for packages ni.  This may take 
a few seconds.
[ rosmake ] rosdep check passed all system dependencies in packages 

[rosmake-0] Starting >>> openni [ make ]
