Google Analytics+ include_once() failed to open stream

Just upgraded to v3.1.1 of Google Analytics + and the WPMU Dashboard this morning, and am now getting this error:

Warning: include_once(/wp-content/plugins/google-analytics-async/externals/dash-notice/wpmudev-dash-notification.php) [function.include-once]: failed to open stream: No such file or directory in /wp-content/plugins/google-analytics-async/google-analytics-async.php on line 67

Commenting out line 67 seems to resolve the issue.

BTW, Analytics+ isn't listed as an option on the forum post form.
