Running bin/civimail.cronjob.php from the command line isn't working in Drupal 7

Running bin/civimail.cronjob.php to send emails isn't working in Drupal 7 and CiviCRM 4. I think it's likely a Drupal 7 bootstrap issue. It still works fine using curl or wget though. Here is the output I got when trying it:

PHP Notice: Undefined index: REMOTE_ADDR in /home/micah/projects/drupal-7.0/includes/bootstrap.inc on line 2597
