Error with Pal2Nal: Can't call method "run" on an undefined value

I am trying to use Pal2Nal through the scripts:

use Bio::Tools::Run::Alignment::Pal2Nal;
$aln = $factory->run($pep_aln, $dnafile);

The system returned the error message:

Can't call method "run" on an undefined value at ...

Anybody knows what the problem is and how I should fix it?

Thanks in advance.
