Maybe I am a retard, but autojump doesn't seem to work on Natty Narwhal

Hello,

I installed autojump in Ubuntu 11.04 from synaptic and I can't get it to work. I added source /etc/profile in my bashrc, closed and opened my terminal again, and whenever I try to use jumpstat it says command not found. I tried to train jumpstat by navigating a bit in my filesystem, but when I try j derp to go to a directory, it also says j: command not found.
