Title: xdebug install error, phpize requires autoconf

Had to install autoconf for phpize to work when installing xdebug. Here's the error output:

```
~ $ brew install xdebug
==> Downloading http://www.xdebug.org/files/xdebug-2.1.3.tgz
File already downloaded in /Users/.../Library/Caches/Homebrew
==> phpize
Configuring for:
PHP Api Version: 20090626
Zend Module Api No: 20090626
Zend Extension Api No: 220090626
Cannot find autoconf. Please check your autoconf installation and the
$PHP_AUTOCONF environment variable. Then, rerun this script.
