xampp / lampp: upgrade PHPUnit in lampp 1.7.1

The default PHPUnit that ships with lampp 1.7.1 is not suited for use with Zend Framework 1.9. The reason is that the PHPUnit version in lampp is to low. So it is necessary to upgrade it using pear. However, before it can be done, pear version that comes with lampp 1.7.1 needs to be also upgraded. The pear executable is in /opt/lampp/bin so I went to this folder.

First PHPUnit channel must be added sudo ./pear channel-discover pear.phpunit.de
Adding Channel "pear.phpunit.de" succeeded
Discovery of channel "pear.phpunit.de" succeeded

Then pear chanels can be updated sudo ./pear update-channels

Then we can try to install PHPUnit:sudo ./pear install phpunit/PHPUnit
phpunit/PHPUnit requires PEAR Installer (version >= 1.8.1), installed version is 1.7.1
phpunit/PHPUnit requires package "pear/Image_GraphViz" (version >= 1.2.1), installed version is 1.1.0
phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5)
No valid packages found
install failed

To upgrade pear I used sudo ./pear upgrade PEAR To check if upgrade was successful I used ./pear -V
PEAR Version: 1.9.0
PHP Version: 5.2.9
Zend Engine Version: 2.2.0
Running on: Linux arch 2.6.31-ARCH #1 SMP PREEMPT Tue Oct 13 13:36:23 CEST 2009 i686

Before PHPUnit can be upgraded, pear/Image_GraphViz package must be upgraded first. So sudo ./pear upgrade pear/Image_GraphViz
downloading Image_GraphViz-1.2.1.tgz ...
Starting to download Image_GraphViz-1.2.1.tgz (4,872 bytes)
.....done: 4,872 bytes
upgrade ok: channel://pear.php.net/Image_GraphViz-1.2.1
and install PHPUnit ./pear install -a phpunit/PHPUnit
phpunit/PHPUnit can optionally use PHP extension "xdebug" (version >= 2.0.5)
downloading PHPUnit-3.4.1.tgz ...
Starting to download PHPUnit-3.4.1.tgz (326,659 bytes)
...................................................................done: 326,659 bytes
install ok: channel://pear.phpunit.de/PHPUnit-3.4.1
After this, when I could use PHPUnit with Zend Framework as described in a tutorial here.
