You'll get better answers from Lincoln or others if you post the question to the bioperl list.

If what you are trying to do is get the exons which should be subfeatures as made by the gene aggregator, then you call the old method sub_SeqFeature 

for my $exon ( $gene->sub_SeqFeature ) {
}

get_SeqFeatures is part of the newer bioperl interface and I don't think Lincoln has updated the DB::GFF code to implement the additions to the interface.
