Is there some point to this exercise?  Why not run apache and put it on 
a different port if you've given 80 to lighttpd?  Anyway, to debug it, 
su to the user the web server is running as (you may need to su -s 
/bin/bash lighttpd if it doesn't have a shell) and try to execute 
BackupPC_Admin.pl.
-r-sr-xr--  1 backuppc backuppc 3995 Oct  5 17:54 BackupPC_Admin.pl
would only be executable if you've added lighttpd to the backuppc group 
- you probably really want it to be group lighttpd.  Also, you'll 
probably need the perl-suidperl package installed.  The idea is that it 
must be executable by (and normally only by) the web user and able to 
change its effective id to backuppc.
