Problems with SQLite3

[eluser]Unknown[/eluser]
Hello,

I'm looking to use SQLite3 with CodeIgniter... I've followed the steps @ http://codeigniter.com/wiki/PDO_SQLite3/, I get this error:

Code:

Fatal error: Call to undefined method CI_DB_pdo_driver::_db_set_charset() in /home/user/domains/domain.com/subdomains/dev/system/database/DB_driver.php on line 171

Any ideas how to resolve this?
