This is a different problem.  The id was not valid.  If you change
KPY1 to KPYK1 it works fine.

$seq = $sp->get_Seq_by_id('KPYK1_ECOLI');
print ref($seq),"\t",$seq->display_id,"\n"
[mike at Wheatley]$ ./bio_quest2.pl

Bio::Seq::RichSeq       KPYK1_ECOLI

If you got this example from the bio perl site would you please post
the url?  Seems to me this same problem has come up before, but I
could not find it in the archives nor on the web site.
