[Bioperl-l] Issues with CLUSTALW

I am new to BioPerl and have no computer science background. I am taking a
bioinformatics course and I have an assignment to write a BioPerl script to
perform the MSA of a specific six sequences, retrieving the sequences from
NCBI and using CLUSTALW.
This is the script I wrote based on a lecture from my course:
$gb = new Bio::DB::GenBank();
$seq1 = $gb->get_Seq_by_acc('NP_000509.1');
$seq2 = $gb->get_Seq_by_acc('XP_508242.1');
$seq3 = $gb->get_Seq_by_acc('XP_537902.1');
$seq4 = $gb->get_Seq_by_acc('XP_001252211.2');
$seq5 = $gb->get_Seq_by_acc('NP_032246.2');
$seq6 = $gb->get_Seq_by_acc('NP_942071.1');
$factory = Bio::Tools::Run::Alignment::Clustalw->new;
@seq_array = ($seq1, $seq2, $seq3, $seq4, $seq5, $seq6);
$seq_array_ref = \@seq_array;
$aln = $factory->align($seq_array_ref);
And this is the error that I receive:
Can't locate Bio/Tools/Run/Alignment/Clustalw.pm in @INC (@INC contains:

I would appreciate any help you can provide.
