Can't comment much beyond what's already been said except that I recently successfully installed Diamondback on a fresh 10.6 machine (MacBook pro).
I was surprised that after running python_select and port installing py26-yaml, I had to also easy_install pyyaml, but after easy_install, everything worked.

"/usr/bin/env python" is the shebang line all ROS python scripts should be using and should get you to whichever Python ROS will actually be using.

So I did "sudo easy_install-2.6 -U pyyaml" and no luck, gave me the same error as before. However, as you suggested I launched python and tried to import yaml and it imported without any problems.
