Path Redirect Admin Screen is Empty

When I navigate to the admin screen for the D7 version of this module (e.g., http://d7-local/admin/build/path-redirect) I get an empty screen. When I mean "empty", I mean that I do a view source and there is literally nothing there. When I then navigate back to a working admin page, I get the following messages in the page header:

========

This is using Drupal 7 HEAD from 27-Nov-2009.

I'm not quite clear is the current D7 build of this module is supposed to work, since it was checked in last on April 26, but thought I'd file this to see where things stand.
