The one issues that I've had with PEAR is a ’file not found’ error. In my experience this is due to the incldue_path setting in PHP. Remeber, the PEAR packages are just libraries of code that you need to include in your programs. If PHP can't find these file then you can't include them.
Warning: date(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /home/astute/www/html/template.php on line 198
