rosdep install -a fails on Debian Sqeeze

edit

Hi all,

Following the guide at http://www.ros.org/wiki/fuerte/Installation/Debian , I get to step 1.5 without issue (as far as I can tell) but when I run rosdep install -a, I get the following:

magus:~/ros-underlay/build# rosdep install -a

I can see that yaml-cpp-sourcedep is not installed and it appears that eigen3 might not be either, but I am not sure where these are supposed to come from.
