Getting gaviota-proxy to work in OS X Yosemite

Some parts taken from: https://gist.github.com/kujohn/7209628

ipfw is officially deprecated and removed in OS X Yosemite. If you don't want to run sudo for gaviota-proxy(which then you can also debug) you have to handle the port forwarding with the program pf.

1. Anchor file

Create file /etc/pf.anchors/mindflash, the port forward needs to match your dev.js config for gaviota-proxy.

#!/bin/sh
# Just copy and paste the lines below (all at once, it won't work line by line!)
# MAKE SURE YOU ARE HAPPY WITH WHAT IT DOES FIRST! THERE IS NO WARRANTY!

function abort {
  echo "$1"
  exit 1
}

set -e

Port Forwarding in Mavericks

---

Since Mavericks stopped using the deprecated ipfw (as of Mountain Lion), we'll be using pf to allow port forwarding.

####1. anchor file Create an anchor file under /etc/pf.anchors/<anchor file> with your redirection rule like:
