Missing env variable using cgi-fcgi standalone

I am testing the my application using cgi-fcgi as a standalone, and
although the application runs some enviromental variables are missing
in the context of the application.
Specifically, REMOTE_USER, which comes from Apache's Auth*
configuration.  Any ideas what might be causing this? (The application
itself is perl)
