hello can anyone tell me what does this line mean? I am executing this script on Mac

use strict; use warnings; use feature 'say'; use Bio::GenBankParser;

my $file = shift; my $parser = Bio::GenBankParser->new( file => $file ); while ( my $seq = $parser->next_seq ) { my $feat = $seq->{'FEATURES'}; for my $f (@$feat) { my $tag = $f->{'feature'}{'locus_tag'}; my $prod = $f->{'feature'}{'product'}; if (defined $tag and defined $prod) { say join "\t", $tag, $prod; } } }

and I got an error like this: @INC (you may need to install the Bio::GenBankParser module) (@INC contains: /Library/Perl/5.18/darwin-thread-multi-2level /Library/Perl/5.18 /Network/Library/Perl/5.18/darwin-thread-multi-2level /Network/Library/Perl/5.18 /Library/Perl/Updates/5.18.2/darwin-thread-multi-2level /Library/Perl/Updates/5.18.2 /System/Library/Perl/5.18/darwin-thread-multi-2level /System/Library/Perl/5.18 /System/Library/Perl/Extras/5.18/darwin-thread-multi-2level /System/Library/Perl/Extras/5.18 .) at script.pl line 4. BEGIN failed--compilation aborted at script.pl line 4.

can anyone tell me how can I parse genbank file if i want to get location product and locus_tag information. I am unable to execute this code.
