Fatal error: Call to undefined function: og_create_links() in group_block.module

This error arises after correcting the previous fixed bug: 'Group actions block perpetually shows 'awaiting approval' where I first reported this error. (found here: http://drupal.org/node/50664 )
The error is:
Fatal error: Call to undefined function: og_create_links() in /home/www/drupal/modules/contributions/modules/gojoingo/modules/gjg/group_block.module on line 99

I have 'apparently' fixed this but without better commenting of the code it is a bit difficult for me to work out what is happening/or should be happening (as a newcomer).

My 'fix' is to change the function name on the last line of this code to match the function name in og.module
Changed
FROM:
$links = og_create_links($node);
TO:
$links = og_og_create_links($node);

This is the relevant section in group_block.module

        if ($row->is_active) {
          $subscription = 'active';
        }
        else {
          $subscription = 'requested';
        }
      }
    }
    $links = array();
    if ($subscription == 'active') {
      $links = og_og_create_links($node);
