Mesos python egg build failure on OS X Mavericks (Xcode 5.1)

The problem (once again) is the fact that the python-egg build-process of distutils grabs the compiler settings from the settings that python was built with.

$ python-config --cflags
-I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -g -Os -pipe -fno-common -fno-strict-aliasing -fwrapv -mno-fused-madd -DENABLE_DTRACE -DMACOSX -DNDEBUG -Wall -Wstrict-prototypes -Wshorten-64-to-32 -DNDEBUG -g -fwrapv -Os -Wall -Wstrict-prototypes -DENABLE_DTRACE

So that is where "-mno-fused-madd" comes from.

I am currently puzzled on why our configuration phase did not detect this problem.
