I'm creating a duplicate package of the eCommerce Table Based Shipping, so I can use the default one for one country, and the duplicate to other countries.

I edited everything so that they didn't have the same class name, etc, but when I install my edited package, I get this error:

Warning: require_once(/htdocs/public/www/concrete/libraries/3rdparty): failed to open stream: No such file or directory in /htdocs/public/www/packages/core_commerce/models/shipping/type.php on line 222 Fatal error: require_once(): Failed opening required '' (include_path='/htdocs/web/libraries/3rdparty:/htdocs/public/www/concrete/config/../libraries/3rdparty:.:/usr/share/php:/usr/share/pear') in /htdocs/public/www/packages/core_commerce/models/shipping/type.php on line 222

Could some one help? Thank you!
