[Fri Dec 11 21:49:38 2015] BackupPC_Admin.pl: Can't use 'defined(@array)'
(Maybe you should just omit the defined()?) at
/usr/share/BackupPC/lib/BackupPC/CGI/Browse.pm line 68.
Compilation failed in require at /usr/share/BackupPC/sbin/BackupPC_Admin.pl

a backup tree to be displayed

Additional info:

Obviously no one used BackupPC since the version of perl was rolled.
Patch is obvious from the Error message.
