Hi,

Following the instructions shown here: http://pysfml2-cython.readthedocs.org/en/latest/building.html#building-with-cython-installed

I'm getting the following error:

I'm build the latest version just pulled from github

Anybody know what I'm doing wrong or missing?

Thanks in advance..

Fixed...

Turns out, version of cython that ships with ubuntu 11.04 is 0.13, removed and easy installed version 0.15. Fixes my problem...

Someone else had the same problem, I added a warning in the documentation since a lot of people use Ubuntu and it's difficult to see where the problem comes from when the error occurs.
