Those launch files are currently in cturtle, so the only thing I can think of is that your stacks aren&#39;t pointed to the right place.  What does an &#39;svn info&#39; in pr2_arm_navigation_tutorials show you?  It should say:<br>
<br><a href="https://code.ros.org/svn/wg-ros-pkg/stacks/pr2_arm_navigation/tags/cturtle/pr2_arm_navigation_tutorials">https://code.ros.org/svn/wg-ros-pkg/stacks/pr2_arm_navigation/tags/cturtle/pr2_arm_navigation_tutorials</a><br>
<br>If it says anything else you will have problems.  <br><br>--Gil<br>--<br>E. Gil Jones (<a href="mailto:gjones@willowgarage.com" target="_blank">gjones@willowgarage.com</a>)<br>Research Engineer<br>Willow Garage, Inc.<br>

Hi Gil,<br>
I had run svn update before compiling. So all the code is latest.<br>
