For those of you following the book instructions on how to install phpunit under linux and if this command doesn't work for you just like in my case:

pear install phpunit/PHPUnit

try to run the following:

pear channel-discover pear.symfony.com
pear install --alldeps pear.phpunit.de/PHPUnit

This solved it for me on CentOS 5x

I had similar problems with Debian 6. Pear alone was not enough. I had to install phpunit using apt-get:

sudo apt-get install phpunit

That resulted in a conflict somehow. After I updated Pear, and removed and reinstalled phpunit it suddenly worked.
