[horde] turba throws error

[Robert Abbate]

Keep getting:

  "Failed to access the address book: Unable to load the definition of
Turba_Driver_."

This is the latest and greatest version of Horde and Turba setup.

Any ideas on this error in Turba?

copy of my sources.php file:

<?php
$cfgSources['localsql'] = array(
    'title' => _("My Addressbook"),
    'type' => 'sql',
    // The default connection details are pulled from the Horde-wide
    // SQL connection configuration.
    //
    // The old example illustrates how to use an alternate database
    // configuration.
    //
    // New Example:
    //'params' => array_merge($conf['sql'], array('table' =>
'turba_objects')),

    // Old Example:
