beware wkhtmltopdf 12.1 on osx 10.9.2

I should work on this more after reading:
https://github.com/adamv/homebrew-cookbook

- I currently have wkhtmltopdf 0.10.0 rc2 running on my OSX 1.9.2 machine
- I would like the latest working one, apparently QT is having trouble with OSX
- QT is a source of pain for wkhtmltopdf
- release setup for wkhtmltopdf was a source of pain
- wkhtmltopdf has some fresh blood/ownership, and mad skillz/changes underway
