Cannot call my installed module

[ShermW0829]

I am trying to get a perl script to run my own installed module. I am getting the below message.

 Undefined subroutine &testdir::testsub called at call_module line 11.

I installed the module using the following code

 module-starter --module=testdir::moduletest --author="Sherman Willden" --email=[e-mail] --license=perl --verbose

The install directory is /home/sherman/module_test/share/perl/5.14.2/testdir/moduletest.pm. I am including the .pm code and the .pl code. The perl file calling the .pm file works when I use require.

 
#! /usr/bin/perl
#
# moduletest.pm
package testdir::moduletest;

use Exporter(); # Why is Exporter white while other use
                # statements are colored

$VERSION = '0.00.01';
@ISA = qw(Exporter);
@EXPORT = qw(testsub);
@EXPORT_OK = qw($string);

sub testsub {
=head1 SUBROUTINE
    The testsub subroutine is just a test 
    function that determines that four variables
    are seen with the testsub function and returns
    a string created within the testsub function.

=cut
    print "In my testsub function\n";
    print "\$_[0]: \"$_[0]\"\n";
    print "\$_[1]: \"$_[1]\"\n";
    print "\$_[2]: \"$_[2]\"\n";
    print "\$_[3]: \"$_[3]\"\n";
    my $string = "My string\n";
    return("$string");
}

1;

Here is the callin perl file's code:

use V5.14.2;
use lib '/home/sherman/module_test/share/perl/5.14.2';

# Since this didn't work I am checking for my path within

print qq(@INC);

# require '/home/sherman/build_dir/testdir/moduletest.pm';

my $moduletest = testdir::testsub(0,2,0,2);
chomp($moduletest);
print "moduletest: \"$moduletest\"\n";
