[Bioperl-l] Error message

I'm a BioPerl novice. I used CPAN to install BioPerl and run the  
following script to test the installation:

use Bio::Perl;
use strict;
use warnings;

my $seq_object = get_sequence('swissprot', "P09651");

write_sequence(">roa1.fasta", 'fasta', $seq_object);

I used as argument both "ROA1_HUMAN" and "P09651". In both cases I  
get the message below.

Any help on the nature of the problem and how to overcome it would be  
greatly appreciated.
