I believe that you're experiencing a capitalization problem. I would write the font names like this:
#!/usr/bin/perl
use strict;
use warnings;
use PDF::API3::Compat::API2;
use PDF::API3::Compat::API2::Util;
my $outputPDF = 'test.pdf';
{
my $pdf = PDF::API3::Compat::API2->new( -file => $outputPDF );
defined $pdf or die "Unable to create PDF file $outputPDF";
my $page = $pdf->page();
my $content = $page->text();
my ( $x, $y ) = ( 72, 720 );
foreach my $fontName (
qw[

)
{
my $font = $pdf->corefont($fontName);
$content->font( $font, 10 );
$content->translate( $x, $y );
$content->text(
'This is the first line I have written using this module' );
$y -= 12;
$content->translate( $x, $y );
$content->text("in quite a while. ($fontName)");
$y -= 12;
}
$pdf->save;
}
