Looks like clang problem. http://stackoverflow.com/questions/22313407/clang-error-unknown-argument-mno-fused-madd-python-package-installation-fa

I had this issue and running

export CFLAGS=-Qunused-arguments
export CPPFLAGS=-Qunused-arguments

before installing fixed the problem. Straight from the SO page. Would this be wise to add to the install script?

I have no idea, I'm not a osx guy. But people on SO seem to suggest it's an issue with clang affecting all python packages that include c modules.

Same problem here but this fix by @cvn does not work for me.

Done like suggested in this comment (http://stackoverflow.com/questions/22313407/clang-error-unknown-argument-mno-fused-madd-python-package-installation-fa#comment34219420_22322645) and it worked for me:
sudo -E pip install watchdog

@chestozo worked perfect, thanks!

From stackoverflow:

UPDATE [2014-05-16]: Apple has fixed this problem with updated system Pythons (2.7, 2.6, and 2.5) in OS X 10.9.3 so the workaround is no longer necessary when using the latest Mavericks and Xcode 5.1+. However, as of now, the workaround is still required for OS X 10.8.x (Mountain Lion, currently 10.8.5) if you are using Xcode 5.1+ there.

@chestozo worked for OSX 10.9, thanks.

sudo -E pip install watchdog
