title: Ansible Installation -clang: error: unknown argument: '-mno-fused-madd'
body: <p>So, I've found some other clang error's on here that appear to be somewhat similar, however, the fixes aren't applicable to my situation.</p>
  
  <p>I'm using OSX Mavericks and we're trying to get Ansible installed.
  I got pip to install correctly, but when I try to install Ansible, I get this clang error.
  We thought, at first, that it might be a version issue, so I re-installed gcc46 after having this same error with gcc49, but I'm still getting the error.</p>
  
  <p>Does anyone know how to fix this?</p>
  
  <p>My complete error report from the pip.log log file is as follows:</p>
  
  <pre><code>cc -fno-strict-aliasing -fno-common -dynamic -arch x86_64 -arch i386 -pipe -fno-common -fno-strict-aliasing -fwrapv -mno-fused-madd -DENABLE_DTRACE -DMACOSX -Wall -Wstrict-prototypes -Wshorten-64-to-32 -fwrapv -Wall -Wstrict-prototypes -DENABLE_DTRACE -arch x86_64 -arch i386 -pipe -std=c99 -O3 -fomit-frame-pointer -Isrc/ -I/System/Library/Frameworks/Python.framework/Versions/2.7/include/python2.7 -c src/MD2.c -o build/temp.macosx-10.9-intel-2.7/src/MD2.o
  
  clang: error: unknown argument: '-mno-fused-madd' [-Wunused-command-line-argument-hard-error-in-future]
  
  clang: note: this will be a hard error (cannot be downgraded to a warning) in the future

  <p>Thanks to anyone who can help me with this. We've spent the past several hours trying to get this to install, and it's starting to get fairly frustrating.</p>
