I don't really use the Bio::Seq* namespace much, so I am not completely sure- but maybe the problem is with this line: 
my $prot = $seq->translate();

..not giving it a 'seq' argument.
UPDATE:
It looks like you have to give translate() a Bio::Seq object, not a Bio::SeqIO object.
Sample input and output would also help ;)
