I've been using BioPerl's Bio::DB::EntrezGene module to retrieve Entrez gene names given the numerical ID. This worked fine for months, and as recently as two weeks ago. Recently, though, it only returns an error. The strangest thing (to me) is that this happens even if I just run the sample code from the documentation. For example, if I run this:

#!/usr/bin/perl

use strict;
use warnings;
use Bio::DB::EntrezGene;

my $db = Bio::DB::EntrezGene->new;

my $seqio = $db->get_Stream_by_id([2, 4693, 3064]); # Gene ids
    while ( my $seq = $seqio->next_seq ) {
            print "id is ", $seq->display_id, "\n";
    }

exit;

I get this:

Replacement list is longer than search list at /Library/Perl/5.12/Bio/Range.pm line 251.

If anyone has any ideas about what might be going on & how to fix it, it'd be much appreciated. Thanks!
