The easiest fix is to open /Library/Frameworks/Python.framework/Versions in the terminal. That directory contains a symlink 'Current', with some luck removing it will re-enable building applications using Xcode, an other alternative it to point the link the version you want to use (you could even link it to /System/Library/Frameworks/Python.framework/Versions/Current). And one final workaround: the configure script has an option named '--with-framework-name=NAME'. This will install the framework as NAME.framework instead of Python.framework. I use this to install multiple build variants of Python, and to keep my regular Python.framework separate from development builds.
