I'm failing to install properly on OSX Snow Leopard, Python 3.2 32/64-bit .dmg from python.org.
Can anyone spot what I'm doing completely wrong? In particular, I'm using 'arch' to run my Python in 32-bit mode, but should I be installing a plain-old 32 bit Python? I'll try that next, but for now...
Running any of the pyglet examples gives:

Sure, that's easy. Pyglet doesn't support Python 3.x yet.

Python 3 for quite a while now (at least on Windows and Linux).
But I think Jonathan was the first one actually trying it on OSX.
I don't know much about MacOS, but I think it should use "cocoa" and
not "carbon" as indicated by the traceback. Maybe the check for
switching between those implementations fails in Python 3?

Although I'm using a Mac as my primary laptop (work influences) I know so little about them that 'carbon' and 'cocoa' mean nothing to me. Given that caveat, I'll have a quick glimpse through the source to see whether it's obvious even to me why one is being chosen over the other. More if I figure anything useful.

Well, that's not quite true. The version in the hg-repo supports
Python 3 for quite a while now (at least on Windows and Linux).
But I think Jonathan was the first one actually trying it on OSX.

One step forward:
Using the same alias 'python' to run in 32 bit mode:
$ python

I think you are missing PyObjC, but I've no experience with that.
Maybe you can try: http://code.google.com/r/evilphillip-cocoa-ctypes2/
As I understand it, this uses ctypes for interfacing with cocoa, not
requiring PyObjC.
And it seems, this will be soon the default implementation in pyglet,
according to this thread:

It's late though, I'm probably doing something dumb. Later, all.

Fascinating, I had not heard that.
