ROS Install - No space left on device, Fresh 16GB SD Card

edit

So I'm installing ROS on a Raspberry Pi with Raspbian, and I'm generally following the debian installation procedure. When I got to step 1.3.2 and tried to run rosinstall ~/ros "http://packages.ros.org/cgi-bin/gen_rosinstall.py?rosdistro=fuerte&variant=desktop-full&overlay=no" everything installs fine except for the visualization_common, gazebo and vcstools packages. I get hit with the following error:

[visualization_common] Installing https://code.ros.org/svn/release/download/stacks/visualization_common/visualization_common-1.8.4/visualization_common-1.8.4.tar.bz2 (version visualization_common-1.8.4) to /home/pi/ros/visualization_common ERROR [vcstools] Tarball download unpack failed: [Errno 28] No space left on device[/vcstools]

After swapping a 4GB SD card for a 16GB SD card, here's the current state of my system (and I'm still getting these "No space left on device" errors!).

pi@raspberrypi:~$ df -h

So, any ideas why ROS might think I have no space left?
