RotoBezier Addon Missing?

Hey, I’m watching a tutorial that involves using the rotobezier tool, but I can’t find it anywhere! I’m currently using 2.67 and the tutorial uses 2.59. Was this tool replaced? I can go back to a previous version, I’m just curious.
The tutorial can be found [HERE]

Use masks instead http://wiki.blender.org/index.php/Dev:Ref/Release_Notes/2.64/Mask_Editor
