It's been a long set of iterations, but I'd like to thank John Wise and Renyue Cen for helping me debug some of the issues with a new version of the OSX installation script designed for Snow Leopard. This will provide a Python installation and a set of associated packages for x86_64 and i386 on OSX 10.6, compiled against the 10.6 SDK.
I've added it to the subversion trunk at trunk/doc/install_script_osx106.sh. If you are running OSX 10.6 and want to give it a shot, please do, and let me know how things go. I think that because it's still experimental, emailing me off list would be the best way to report bugs and other concerns.
