I was doing the AthensTutorial and there is something I dont understand so I created a stackoverflow question.

Can be found here -> http://stackoverflow.com/questions/16034694/in-athenstutorial-where-canvas-comes-from

AthensTutorial does not work on Ubuntu 12.10 amd64 since it requires cairo32bit and ubuntu comes with 64bit libs of cairo

should i file that as a bug ? I have not found a way to install cairo32 bit in my ubuntu yet.
