VS 2008, Windows Server 2008 64-bit

I just installed the tool on VS 2008, Win Server 2008 64-bit. I created a new WSPBuilder project. When I try to add a sequential workflow feature I get an error: 'The assembly reference "microsoft.office.workflow.tasks [...]" could not be added to the project. [...] ' I tried changing the target framework of the project to the .NET Framework 3.5 but it didn't help. Any ideas?
 Also, is there a dependency on MOSS by any chance?
thanks,
