Erroneous message on Wordpress install in 4.6b3

I installed a fresh version of Civi 4.6b3 on top of a fresh Wordpress 4.1.1 install. It's a very trivial issue, but upon successful installation I received these two messages:

CiviCRM has been successfully installed
You need to define CIVICRM_DSN in civicrm.settings.php

The first one was true; however, the CIVICRM_DSN was already defined. Looking at CRM/Core/Config.php where this error is generated, it seems like this check gets made every time CiviCRM is called, so clearly it's just that CIVICRM_DSN isn't defined at the very moment the install finishes. It might be worth suppressing this message on initial install just to provide a better first impression to first-time installers.
