I used CGI::Carp and CGI::Debug. You can customize all your error messages and go from there. The BEGIN block redirects the error message to the browser and prints out the message with a little extra from CGI::Debug. 
#!/usr/bin/perl

use strict;
use warnings;
use CGI;
use CGI::Debug;
use CGI::Carp qw( fatalsToBrowser );

BEGIN {
    sub carp_error {
        my $error_message = shift;
        my $q = new CGI;
            $q->start_html( "Not able to create directory" ),
            $q->h1( "Error" ),
            $q->p( "Not able to create directory" ),
            $q->p( $q->i( $error_message ) ),
            $q->end_html;
    }
    CGI::Carp::set_message( \&carp_error );
}

system("mkdir -p test");
if ($@) {
    print "Not able to create directory\n";
}
