PEAR breaks on upgrading to PHP5
After enabling PHP5 using the control panel, I found that my web application didn't work. Scary!
Turns out that DreamHost's installation of PHP5 has a different include path than PHP4 did, so you have to tell it where to find the PEAR libraries. To fix this, add this in your PHP configuration file:
set_include_path( get_include_path() . PATH_SEPARATOR . '/usr/local/lib/php' );
