Drupal module's list of permissions are stuck - permissions

Question

From what I understand, my problem is that I am (rather, my client is) running an older version of Drupal, specifically Core 6.26 If you're curious about any additional specs, I'll be happy to divulge.
With that out of the way, I made a new module with the following menu hook.
function checkin_menu(){
$items = array();
$items['checkin'] = array(
'title' => 'Checkin'
,'type' => MENU_CALLBACK
,'access arguments' => array('checkin')
,'page callback' => 'checkin'
);
}
The permissions listed out exactly what I expected. There was a section called "Checkin" the same as the module's name as specified in the .info file, and one item to give permissions to "checkin"
Later on I expanded the module to have two different paths. The second one is supposed to be for admins only.
function checkin_menu(){
$items = array();
$items['checkin'] = array(
'title' => 'Checkin'
,'type' => MENU_CALLBACK
,'access arguments' => array('create a checkin')
,'page callback' => 'checkin'
);
$items['checkin_admin'] = array(
'title' => 'Checkin Admin'
,'type' => MENU_CALLBACK
,'access arguments' => array('view all checkins')
,'page callback' => 'device_checkin_page'
);
return $items;
}
Much to my surprise neither "create a checkin" or "view all checkins" is showing up. I still have the original "checkins" showing on the permissions page. I've been hunting for answers for a couple days now. Help a guy out?

Permissions are defined by a different hook, which is hook_perm.
So you should be doing something like this:
/**
* Implementation of the hook_perm()
*/
function checkin_perm() {
return array (
'create a checkin',
'view all checkins',
);
}
