"Unable to find the component class" error when switching to Form view

I'm currently trying to port FreeShip+ to non-Windows-OS using
Lazarus.
Whileas I managed to get it to compile with FreePascal 2.6.0/Lazarus
1.0RC1 (still no luck running it, but this is work-in-progress), I've
run into some problems with the IDE.
I'm new to FPC, so please be kind...

When trying to switch from Unit view to Form view (F12), I have some
units where it is not possible to get a preview of the form layout.
The IDE throws the following error:

QuoteUnable to find the component class "TFreeShip".
It is not registered via RegisterClass and no lfm was found.
It is needed by unit:
/home/soenke/FS_src/Forms/Main.pas

[Ignore, us TForm as ancestor]   [Abort whole loading]   [Cancel
loading this component]
Class is declared as follows
Code: [Select]      TFreeShip             = class(TComponent)
                                 private     { Private declarations }
// ... 
Implementation section also contains
Code: [Select]procedure Register;
begin
    RegisterComponents('FreeShip', [TFreeShip]);
// Also tried without luck:
//    RegisterNoIcon([TFreeShip]);
//    RegisterClass(TFreeShip);
end;{Register} 
Maybe I have overseen something, but at the moment I'm absolutely
clueless.

Thank you very much in advance for your replies,
Sönke

You have to create a package containing the component and register it
to the IDE, otherwise the IDE would have no idea how to stream the
component.

OK, just wonder about the sense of the "[Ignore, use TForm as
ancestor]" option.

Thanks for your reply.
