That means you didn't configure it to run as a cgi script.  Most 
distributions already have a cgi-bin directory somewhere with a 
scriptalias or other config setting to make it execute programs. Just 
put the BackupPC_Admin program there.  When running this way it needs to 
be readable and executable by the apache's group (www-data?) and owned 
and setuid to the backuppc user.

That should work with mod_perl.  If you mean the admin user after 
logging into the web interface, that has to do with web authentication 
not linux users or permissions.

That shouldn't be set to root.

Doesn't debian hava a packaged version you can install with apt-get?

Backups should run without the web interface if you set up the config 
files by hand.

You don't need a patch, you just need to configure apache.  And I still 
recommend not using mod_perl.
