Install mcrypt PHP extension in OSX 10.10 using Homebrew

For those of you using Laravel and trying to run composer install and getting an mcrypt error (Laravel requires the Mcrypt PHP extension.), this will fix it for you.

I use homebrew and have php 5.6 installed.

for mcrypt:

$ brew install mcrypt

for the mcrypt php extension:

$ brew install php56-mcrypt

It's really that easy.
