更新成功后，PEAR已经是1.9.1版了，现在可以放心地安装PHPUnit了：
D:xamppphp>pear install phpunit/PHPUnit
Unknown remote channel: pear.symfony-project.com
Unknown remote channel: pear.symfony-project.com
Unknown remote channel: components.ez.no
Unknown remote channel: components.ez.no
phpunit/PHPUnit requires package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/PHPUnit can optionally use PHP extension "dbus"
phpunit/DbUnit requires package "channel://pear.symfony-project.com/YAML" (version >= 1.0.2)
phpunit/PHP_CodeCoverage requires package "channel://components.ez.no/ConsoleTools" (version >= 1.6)
phpunit/PHP_CodeCoverage can optionally use PHP extension "xdebug" (version >= 2.0.5)

上面信息来看，还是没有安装成功，pear.symfony-project.com和components.ez.no两个频道也要添加一下：
D:xamppphp>pear channel-discover pear.symfony-project.com
Adding Channel "pear.symfony-project.com" succeeded
Discovery of channel "pear.symfony-project.com" succeeded
D:xamppphp>pear channel-discover components.ez.no
Adding Channel "components.ez.no" succeeded

再次尝试安装PHPUnit：
D:xamppphp>pear install phpunit/PHPUnit
phpunit/PHPUnit can optionally use PHP extension "dbus"
phpunit/PHP_CodeCoverage can optionally use PHP extension "xdebug" (version >= 2.0.5)
