Delphi 3 doesn't seem to come with premade projects for rebuilding it's various pieces. But I need to recompile vcldb30.dpl because I've changed dbctrls.pas and I distributing the software with run-time packages. There was a bug with intelimouse driver and TDBLookupComboBox. I've solved it modifiying dbctrls.pas but now I need the new VCLDB30.DPL.
