Kyle Stewart has just announced on the Doryen forums the availability of a python port of libtcod. You can download it there :

It's based on the 1.2.2 version, works for Windows and Linux, seems pretty complete and even has an improved version of the Field of View toolkit, using permissive field of view. Thanks a lot to him, and happy coding to all the python roguelike developpers !
