Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

Raspberry Pi
Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
- You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.

PSA :

just use GHC for OSX https://ghcformacosx.github.io

the rest of these directions are preserved for historical purposes

TLDR version, if you have homebrew

xcode-select --install ; brew tap homebrew/versions ;   brew tap homebrew/dupes \

	//UPDATE: This gist has been made into a Node.js module and now can be installed with "npm install js-crawler"
	//the Node.js version does not use Phantom.JS, but the API available to the client is similar to the present gist

	Some notes on remote debugging mac builds on Travisci. It's hard to tell when something hangs what the cause it. Trial and error via commits is tedious. And on Mac , sometimes it's the gui asking for input. So I worked my around to get the access I needed for faster debugging a build.

	# Add a key so we can login to travisci vm
	- cat ssh/travisci.pub >> ~/.ssh/authorized_keys
	- chmod 600 ssh/travisci

	# Install netcat
