nodequeue not designated as a dependency

The nodequeue module isn't designated as a dependency in the nodequeue_annotate.info file. I tried enabling nodequeue_annotate without enabling nodequeue first and instead of prompting me to install nodequeue, I received the following error messages…

$ drush dl nodequeue nodequeue_annotate && drush -y en nodequeue_annotate
