@sperkins please re-download the packages, if you’ve downloaded them long ago. Maybe there are new and improved packages there, I’m not sure.
Anyway: please try copying those three files mentioned above from GitHub into your installation, and then retry the upgrade:
include/SugarEmailAddress/SugarEmailAddress.php
include/SugarEmailAddress/getEmailAddressWidget.php
modules/Configurator/Configurator.php
