Grab PEAR via CVS is you need it
Quick note that the PEAR installer is missing (go-pear.org has expired and has been snapped up by some cybersquatters) and http://pear.php.net/go-pear renders a 404. So the current solution is to grab the go-pear install from CVS:
curl
"http://cvs.php.net/viewvc.cgi/pearweb/public_html/go-pear?revision=1.11
8&view=co" | php
Cool the pearweb crowd have fixed go-pear via http://pear.php.net/go-pear :)
