Trying to install gevent using Homebrew on OSX 10.11 latest public beta. When running the install, it outputs the following errors (Sorry for the large wall of code, not sure exactly where the error is)

use CFLAGS='-std=c99' pip install gevent to fix this.
on OS X 10.11, clang uses c11 as the default, so just turn it back to c99.

I ran into the same issue on my OSX 10.10.5, trying to install flask-socketio, which has gevent as a dependency, but:
sudo CFLAGS='-std=c99' pip install flask-socketio
gave me
Successfully installed flask-socketio-0.6.0 gevent-1.0.2 gevent-socketio-0.3.6 gevent-websocket-0.9.5
So, tonicbupt's answer worked for this too.

I wasted my time for two days and the solution below for Mac users...
pip install gevent==1.1b5
Solution: gevent fails to install in a python virtual environment on OS X Capitan
