Happens with teapot 2.6 as well.

@Teteros Thanks for this. As it turns out, teapot is not Python 3 compatible at the moment.

I'm not sure how much time it would take to add support for it but a PR would most certainly be welcome !

It's alright, I was able to compile freelan manually anyway due to great legibility the .party files offer.

If anyone else was struggling to build this on python 3, it seems you also need the git version of the progressbar module not uploaded yet on pypi because of NiltonVolpato/python-progressbar#54.
