"TypeError: can't concat bytes to str" in pyglet.font.carbon on Mac OS using python3 (potential fix linked)

[GoogleCodeExporter]

I have patched my copy here by adding an explicit bytes reference:

Have you tried Pyglet 1.2 alpha1 or the repository code? Yes

What steps will reproduce the problem?
1. On MacOS 10.5 running python3.4 and the repo code.
2. Create a pyglet.text.Label object

Paste in the traceback or error message:
