A call to DB::connect(--) Never Returns

I have PHP 4.2.3 and was trying recipe 10.2 from the "PHP Developer's Cookbok". In the example a call is made like this: print "Before call"; $dbh = DB::connect('testDB://scott:tiger@localhost/SITE_SESSIONS, true); print "After call"; if (!$dbh) { die(sprintf('Error [%d]: %s', $dbh->getCode, $dbh->getMessage())); } Only the "Before call" comes back leading me to believe DB:connect(--) somehow just got lost. I did have to change the name of PEAR.php.in to PEAR.php before I could even get to first base if that makes a difference. TIA............Louis Abeyta
