Still mystified by mod_wsgi traceback ...

I posted the traceback I'm getting -- http://dpaste.com/293813/
I'm still completely mystified. The traceback directs me to:
"Edit your MIDDLEWARE_CLASSES setting to insert
'django.contrib.auth.middleware.AuthenticationMiddleware'
before the RemoteUserMiddleware class." But looking further
up in the traceback, it sees that d.c.a.m.AuthenticationMiddleware
*is* there, and it's true -- I already have it in my
MIDDLEWARE_CLASSES setting before the RemoteUserMiddleware class,
so how could mod_wsgi possibly not be finding it?

See below for more details on my configuration ...
