ImportError: No module named staticfiles

[EricSI]

I'm running Django 1.3.1.  On my staging server I am getting this error message through the email error log only.  The error does not appear to manifest itself in how the site is rendered, all of my static files are actually showing up correctly.

I find this error odd for a couple of reasons.  One being that staticfiles is automatically included in contrib in Django 1.3+, and two being that I have DEBUG=True in my settings, I would figure that when a page is rendered that I would get the error information display on the page instead.

I have my site running on a dev server and a staging server.  The two servers are setup identically, yet this is only occurring on the staging server.

Both servers are Ubuntu running Apache with mod_wsgi.

Does anyone have any idea why I might be getting this error?
