Yes, thanks -- that got me much further in the process. Here are the other
changes I had to make to get "rosmake -a" to complete:

   - I had to add a "ros" package to rosdep-fedora.yaml to allow "rosdep
   install -a" to work. I ended up just giving an empty list of yum packages
   and that seemed to work.
   - the manifest.xml for pcl refers to pkg-config things like
   pcl_common-1.5, while the pcl RPM installs un-versioned pkg-config things,
   so I had to change that both in the installed pcl manifest and in the
   copied version in perception_pcl/pcl_ros/manifest.xml. I also added
   `mysql_config --libs` to the ldflags list because libmysqlclient.so is in a
   subdirectory of /usr/lib64.
   - added more rosbuild_link_boost ($executable system) calls to
      - diagnostics/diagnostic_updater/CMakeLists.txt
      - added more instances of "set(PythonLibs_FIND_VERSION 2)" and
   rosbuild_link_boost($executable system) to CMakeLists.txt's as needed
   - added the following to laser_pipeline/laser_filters/CMakeLists.txt
      -
      -
      include_directories(${CMAKE_CURRENT_SOURCE_DIR}/../../perception_pcl/pcl_ros/include)
      -
      link_directories(${CMAKE_CURRENT_SOURCE_DIR}/../../perception_pcl/pcl_ros/lib)
   - added protobuf to the generated .rosinstall as described at
   https://code.ros.org/lurker/message/20120411.124910.6ccbec56.el.html

So this all worked fine, and then I tried to rosmake the code provided by
the students ...

Failed to invoke /opt/ros/fuerte/bin/rospack deps-manifests social_robot
[rospack] Error: package/stack social_robot depends on non-existent package
opencv2


Arrggghhh ... does this mean that I need a manifest.xml for opencv-devel
too, or something like that?

Increasingly tempted to just jump ship to ubuntu and be done with it, but
I'm stubborn. :)
