I take it that nothing extra needs to be done to use the SAPI module in 5.3? http://us.php.net/manual/en/migration53.sapi.php Edit: saw this in the logs: Warning! a PEAR user config file already exists from a previous PEAR installation at '/root/.pearrc'. You may probably want to remove it. Wrote PEAR system config file at: /usr/local/lsws/lsphp5/etc/pear.conf You may want to add: /usr/local/lsws/lsphp5/lib/php to your php.ini include_path Should I perform those actions?
