This fork allows you to easily use PHPUnit 3.5 (dev) without manually downloading all dependencies nor editing you php.ini include path.
It will only be useful until the official PHPUnit3.5 release.
git clone git://github.com/knplabs/phpunit-easyinstall.git phpunit
cd phpunit
git submodule init
git submodule update
Now you can enjoy phpunit 3.5!
php phpunit.php
Optionally you can add a symbolic link to your phpunit.php:
sudo ln -s /home/me/.../phpunit/phpunit.php /usr/local/bin/phpunit
