[New-bugs-announce] [issue14499] Extension module builds fail with Xcode 4.3 on OS X 10.7 due to SDK move

[Ned Deily]

New submission from Ned Deily <nad at acm.org>:

With the release of Xcode 4.3 for OS X 10.7, Apple has moved the location of the OS X SDKs from their long-time path of /Developer to within the new Xcode.app bundle itself.  This breaks the building of extension modules with any of Distutils or packaging/Distutils2 when Python was built as as universal build with an SDK in the former location, as is the case with the python.org installers.

A workaround is to either leave the old /Developer directory in place when upgrading to Xcode 4.3 or to install a symlink to the new location:

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer /Developer
