When I try to install and build ROS electric from source, rosdep complains about not being able to find certain packages. These packages are not in the Ubuntu repositories, so where am I supposed to get them?

One such package is yaml-cpp0.2.6-dev.

I didn't have this problem, so you probably omitted an installation step or so. ROS repositories provide yaml-cpp0.2.6-dev, so if you cannot install it with

sudo apt-get install yaml-cpp0.2.6-dev

it means that you probably didn't set up your sources.list properly (read here, depending on your Ubuntu version). Remember to set up your keys and update apt-get's lists afterwards:

wget http://packages.ros.org/ros.key -O - | sudo apt-key add -
sudo apt-get update

Now yaml-cpp0.2.6-dev should be there for you.

This is true. Even when doing ROS completely from source, there are a few other packages outside of ROS that the ROS repositories provide. So even when doing a source install, you have to add the repositories to apt.
