Update: I got it to work.

@Kim: I had not checked that entry in the rosdep.yaml file. It could have
been the reason.

@Josh,Kim: I was using the "pre-compiled binaries install" instructions from
this page:
http://www.ros.org/wiki/ROS/Installation/Ubuntu/Deb#Ubuntu_install_.28Pre-compiled_binaries.29
but, it appears that the following line does not work...

deb http://code.ros.org/packages/ros/ubuntu lucid main

...because the URL http://code.ros.org/packages/ros/ubuntu/ does not have a
'dists/lucid' directory. Instead, I tried Hardy (8.04) which was linking
libboost-xx-37 instead of libboost-xx-40. Then I cleaned up and used  the
Karmic repository and it works fine. I tested it with turtlesim and some of
the other beginner tutorials. Thank you both for the follow-ups!

New issue: When I tried rviz, the table and coffee cup run well in gazebo,
but the PR2 model does not load. My linux just freezes when I run "roslaunch
pr2_gazebo pr2.launch". From one of the previous forum posts, it looks like
I ran into a DRI/graphics card issue with my Intel GM965/GL960 graphics
controller.
