Subject Looking for TIB_Import

I have installed IBO 4.2.Fn on Delphi 4 C/S, but I can't find
TIB_Import in the palette.

I have tried openning IB_Import.pas and "Components-Install
Components" into existing package IBO40TDT_D4.dpk, but I obtain an
error because the package already contains IB_Import unit...

What I'm doing wrong?

Thank you in advance...
