I have a file, tmp.pl, and wish to include my own perl module file, util.pm:

package util;

our @EXPORT = qw(execute);

sub execute {
    my $cmd = shift;
    my $return = 'exit';
    my $die = 1;
    if ($return !~ m/^(exit|stdout|stderr|all)$/i) {
        die "you gave $return = "$return", while this subroutine only accepts ^(exit|stdout|stderr)$";
    }
    my ($stdout, $stderr, $exit) = capture {
        system( $cmd )
    };
    if (($die == 1) && ($exit != 0)) {
        say STDERR "exit = $exit";
        say STDERR "STDOUT = $stdout";
        say STDERR "STDERR = $stderr";
        die "$cmdn failed";
    }
    if ($return =~ m/^exit$/i) {
        return $exit
    } elsif ($return =~ m/^stderr$/i) {
        chomp $stderr;
        return $stderr
    } elsif ($return =~ m/^stdout$/i) {
        chomp $stdout;
        return $stdout
    } elsif ($return =~ m/^all$/i) {
        chomp $stdout;
        chomp $stderr;
        return {
            exit   => $exit, 
            stdout => $stdout, 
            stderr => $stderr
        }
    } else {
        die "$return broke pigeonholes"
    }
    return $stdout
}

1;

which I include in the current directory thus:

#!/usr/bin/env perl

use Cwd 'getcwd';
push @INC, getcwd();
use util;
use warnings FATAL => 'all';
use autodie ':default';

which gives me an error:

Can't locate util.pm in @INC (you may need to install the util module) (@INC entries checked:

How can I include the simple module in a directory with other scripts?
