[Plugin: WP Easy Post Types] Numerous warnings when WP_DEBUG is true

Using Easy Post Types 1.0.1 on WP3.1.

I have WP_DEBUG set to true in wp-config.php as I am developing a theme.

When I use EPT I see numerous warnings and the PHP error messages are breaking the plugin.
The one that is always shown:
Notice: Use of undefined constant TEMPLATEPATH – assumed ‘TEMPLATEPATH’ in /wp-content/plugins/easy-post-types/classes/custom-checkbox/custom-checkbox.php on line 33

In Add New Field modal dialog:
Notice: Undefined variable: content_type in /wp-content/plugins/easy-post-types/templates/field-form.php on line 89
Notice: Undefined index: menu_position in /wp-content/plugins/easy-post-types/boxes/admin-interface.php on line 96

Notice: Undefined variable: field_to_show in /wp-content/plugins/easy-post-types/boxes/admin-interface.php on line 12

I will turn off WP_DEBUG for the moment.
