missing dependency for pcl_tutorials

edit

I'm trying to rosmake pcl_tutorials and receive the following error:

tim@Linux-laptop-1:~/ros_workspace/pcl_tutorials$ rosmake --rosdep-install pcl_tutorials [ rosmake ] Packages requested are: ['pcl_tutorials']
[ rosmake ] Logging to directory/home/tim/.ros/rosmake/rosmake_output-20110914-153143
[ rosmake ] Expanded args ['pcl_tutorials'] to: ['pcl_tutorials']
[ rosmake ] Generating Install Script using rosdep then executing. This may take a minute, you will be prompted for permissions. . .
Failed to find rosdep libtiff for package pcl_tutorials on OS:ubuntu version:natty [ rosmake ] rosdep install failed: Rosdep install failed
tim@Linux-laptop-1:~/ros_workspace/pcl_tutorials$

======

Any suggestions?

I did also tried to add/update the libtiff using Synaptic pkg manager but no difference.

Thanks
