Q:

OS X Pillow installation error

I followed this instructions: http://pillow.readthedocs.org/en/latest/installation.html#mac-os-x-installation
$ sudo pip install Pillow

returned error: 
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

error: command 'cc' failed with exit status 1

Please, help me!
UPDATE:
I installed PIL before. After installation I tried some black magic to make PIL work with libjpeg. And then I tried to reinstall PIL. It was uninstalled, but failed to install.

A:

There seems to be something broken when running XCode 5.1. Had the same problem when installing pycrypto.
Try this:
ARCHFLAGS=-Wno-error=unused-command-line-argument-hard-error-in-future pip install Pillow
