I'm trying to extend Log::Log4perl so that I can trap all messages for a process and, at the end, format them all nicely in an email. The example I have below only deals with error messages to more simply demonstrate my issue.

I'm using perl 5.8.2 and Log::Log4perl 1.22

Here is my logger package: 

package Mylogger;

use warnings;
use strict;

use base qw(Log::Log4perl);

my @error_msgs;

sub init {
    Log::Log4perl::init(@_);
    return;
}

sub get_logger {
    $Log::Log4perl::caller_depth = 1;
    my $logger = Log::Log4perl::get_logger(@_);
    bless $logger, __PACKAGE__;
    return $logger;
}

sub error {
    my ($this, $msg) = @_;
    push(@error_msgs, "ERROR $msg");
    $this->SUPER::error($msg);
    return;
}

sub get_logged_errors {
    return \@error_msgs;
}

1;

Here is my test program: 
use strict;
use warnings;
use FindBin;
use Mylogger;

my $conf = q(
    log4perl.rootLogger=DEBUG, Screen
    log4perl.appender.Screen         = Log::Log4perl::Appender::Screen
    log4perl.appender.Screen.stderr  = 0
    log4perl.appender.Screen.layout=PatternLayout
    log4perl.appender.Screen.layout.ConversionPattern=%d{ISO8601} %-5p
+ %C %m%n
);

Mylogger::init(\$conf);

my $log = Mylogger::get_logger();

$log->error('error 1');
$log->error('error 2');

Here is a run of my test program showing two errors: 
#test.pl
Can't locate object method "error" via package "Mylogger" at Mylogger.
+pm line 25.
Can't locate object method "DESTROY" via package "Mylogger" at /usr/op
+t/perl5/lib/site_perl/5.8.2/Log/Log4perl/Logger.pm line 60.
END failed--call queue aborted.

The error on line 25 in MyLogger is the call the SUPER::error, which somehow cannot be found. Also there is some issue with the way I'm implementing this which causes Log4perl to not find a DESTROY method. What am I missing here?
