iTransact module has invalid include statement

At iTransact module in function _itransact_process first line is this:
include_once 'modules/ecommerce/contrib/eway/eway.inc';

This will work only if php.ini include statement has root directory of drupal in include path.

More approriate change would be this:

require_once (drupal_get_path('module', 'eway') .'/eway.inc');
