So it appears to be getting the feed. I also did a dump of $entries[ 0 ] which gave me:

$VAR1 = bless( {
                 'ns' => 'http://www.w3.org/2005/Atom',
                 'elem' => bless( do{\(my $o = 140714248)}, 'XML::LibX
+ML::Element' ),
                 'version' => '0.3'
               }, 'XML::Atom::Entry' );

So....works for me! Sorry.
