With my new job comes a new MacBook Pro (the latest generation, very slick!). The Setup Assistant did a great job of making my new MBP just like my old one, carrying across all of my applications and settings from my latest Time Machine backup. Everything in /usr/local/bin made it. Ditto for my MacPorts stuff in /opt.
One thing that didn’t make it was the Python libraries that I had installed in the system-wide site-packages directory (/Library/Python/Version/2.5/…). The Setup Assistant is designed to not pull OS parts across when you are loading up a new machine. That makes sense, but unfortunately the Python stuff seems to fall into that category.
Perhaps the site-packages directory should be moved to /usr/local or something so that it gets copied over? A change like that would be useful for Apple to make.
Thankfully, the impact on me is pretty minimal, because I tend to do my work in virtualenvs and don’t have very many packages installed system-wide.
