required package: "dcldb50.bpl" not found


I am trying to compile a Turbopower library (Flashfiler 2) and its
examples. I am working under delphi 5.0.  I am getting the message
"required package dcldb50.bpl" not found.  Is this a part of Delphi
5.0 standard or is it only with the professional version?

Any help appreciated.
