How can this happen?

    jon@vaio:~/brickify$ /usr/bin/node -v

    v0.8.11

    jon@vaio:~/brickify$ echo $PATH

    /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

    jon@vaio:~/brickify$ node -v

    jon@vaio:~/brickify$

/usr/bin is in $PATH, so just writing node -v should work the same as writing /usr/bin/node -v
