APM: problems with BackupPC

[lists at chrisbaker.net]

I am working with a program called BackupPC. It has a lot of PERL scripts.
 I am on Fedora Core 8. I know that Apache is working because I get the 
Apache test page in the web browser.

When I try to access this site: <server/cgi-bin/BackupPC_Admin>, I get
this message:

> Error: Unable to read config.pl or language strings!!
>
> Note: $ENV{REMOTE_USER} is not set, which could mean there is an

Permissions seem to be okay. I am trying best I can to duplicate a working
 installation of BackupPC.
