in reply to GD::Barcode::QRcode and perl2exe

you probably forgot to pack the files perl2exe didn't know to pack , standard faq item for all packers par/pp,perlapp,cavapack ... only fatpacker uses .packlist without trying to be clever (remove unused files)

OTOH, the version you listed is quite ancient
