Meta Boxes on different post types

Hi,
I am using the meta-box plugin, I want different meta boxes on both ‘posts’ and a new ‘custom-post-type’, but is seems I cannot do both, it will only do the last call, I have switched to order and the last call only will have meta boxes!.

In one function for normal posts I have

$meta_boxes[] = array(
  'id' =>    $prefix.   'general',
	'title' => 'Defaults',
	'pages' => array( 'post'),

In another function for custom posts I have

$meta_boxes[] = array(
  'id' =>    $prefix.   'general',
	'title' => 'Defaults',
	'pages' => array( 'custom-post-name'),

I do not want to bundle the plugin’s code inside my plugin, I am trying to do it so when the plugin is updated the users will be able to use the auto update.

Regards

David
