CiviGroup Role Sync module referencing api/v2 causing error

When using the CiviGroup Role Sync module, I was getting a consistent 'Failed opening required 'api/v2/GroupContact.php' error when I would remove a contact from a group that was being synced to a Drupal role. I found the reference to API v2 on line 243 of the civicrm_group_roles.module file. Removing the line entirely allows the module functions as expected. I searched JIRA and found an existing ticket for this error, but it seems as though only the 7.x- branches have had the fix applied for Civi 4.4, not the 6.x- branches.

For reference that issue is here: https://issues.civicrm.org/jira/browse/CRM-16414

This line still exists in the 6.x-4.3, 6.x-4.4, and 6.x-4.4.6.x branches on these lines:
