PEAR wbesite down and Selenium problems

Hi guys!

So I’m at page 45 where I’m asked to install phpunit with PEAR but when I go to the website is down and it’s been two days like that. Is ti my browser or is the site really down? if so, where can I download PEAR?

The other thing, the book says to install Selenium RC but, when I go the webpage there are like a hundred of available downloads .-. I don’t know which one to pick. Can someone help me?
