Нужна помощь в обновлении PEAR для установки PHPUnit

Я пытаюсь установить PHPUnit с PEAR. Вот я и бегу...

PEAR Version: 1.7.2
PHP Version: 5.3.8-ZS5.5.0
Zend Engine Version: 2.3.0
Running on: Windows NT L-PC 6.1 build 7600 (Windows 7 Home Premium Edition) i586

Когда я пытаюсь установить, я получаю сообщение об ошибке, в котором говорится, что мне нужно обновить PEAR...

C:\Program Files (x86)\Zend\ZendServer\bin>pear install phpunit/PHPUnit
Did not download optional dependencies: phpunit/PHP_Invoker, use --alldeps to download automatically
phpunit/PHPUnit requires PEAR Installer (version >= 1.9.4), installed version is 1.7.2
phpunit/PHPUnit requires package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/PHPUnit can optionally use package "phpunit/PHP_Invoker" (version >= 1.1.0)

No valid packages found
install failed

Поэтому я полагаю, что мне нужно обновить PEAR. Я запустил грушу, обновил грушу и получил следующее...

C:\Program Files (x86)\Zend\ZendServer\bin>pear upgrade pear
pear/Console_Getopt requires PEAR Installer (version >= 1.8.0), installed version is 1.7.2

Но не обновляется. Когда я повторно запускаю версию груши, она показывает, что я все еще на 1.7.2. Как я могу это исправить?
