The binaries will still be built against python.org Python, so there
shouldn't be an issue here. Same for building from source.

Yeah, I still have an OS X 10.6 machine and Accelerate works great there.
But they screwed it up pretty bad in 10.7, and then made it worse for 10.8.
Not so cool anymore....

It would be nice to keep it that way.

I think we have to indeed keep it easy to build from source. Maybe
providing a script to automatically fetch all dependencies and then build
(like MPL does) would be a good way to go.
