(off-topic, but could you please try the perception_pcl stack instead? We're trying to identify bugs there in order to
robustify it and make a 1.0 release. Thanks)

That doesn't really work, as sudo won't correctly preserve your variables as far as I can tell. A solution is to re-run
your setup.sh. Another solution would be to chmod/chown those files so that your user has write permissions there.
In either case, I would recommend that you don't try that, but instead create a new package and add the tutorial that
you want to compile to that package. Make sure the new package is in your ROS_PACKAGE_PATH, and make it depend on pcl.
The rest should work.
Btw, all the online tutorials are already compiled and provided for you as part of the pcl_tutorials package (in its
newer incarnation, part of perception_pcl_addons)

PS. Please use
pcl-users@code.ros.org for PCL issues. That should help us centralize similar problems/answers in the
future. Thanks.
Cheers,
Radu.
