Hello, I'm having trouble with pyobj since I have installed Python 2.6.4 by official dmg download here. 
Befor I used python pre-installed in Snow Leopard and everything worked ok. Now I can't import pyobjc.
I tried to perform easy_install pyobjc but I can't still import objc. 
The strangest thing is that it works for previos version!
Here some log:
rmacbpro:~ riccardorotondo$ python
