Python compilation failure on Yosemite

[staticfloat]

After working around #33242, I have come across this error when attempting to install python on OSX 10.10:

Here is the relevant config.log. This is on a clean Yosemite install, with Xcode 6.0.1 and a clean brew doctor (other than it suggesting to install Xcode 6.1, which isn't available yet for me).

Xcode 6.0.1 doesn't include the 10.10 SDK - you need Xcode 6.1 or the 6.1 CLT to build software on Yosemite. I've heard it may be available to download manually?

I can download Xcode 6.1 here without developer program membership: https://developer.apple.com/downloads/index.action

I can download the CLT, not Xcode proper. The CLT is enough for Homebrew though. :)
