Importing Winforms controls in VCL.NET

(My previously-posted question must've slipped under the radar, so I'm 
trying again)

Has anyone successfully imported a 3rd party Winforms .NET control for use 
in BDS 2006 VCL.NET? If so, please shed some light on how you got it to 
work.

The several times I've tried using the "Winform Controls Package"
wizard 
(e.g., extrapolating from the steps found at 
http://dn.codegear.com/article/31886), when I attempt to "Add..." the

resulting assembly to the .NET VCL Components tab, I get one of two error 
boxes:

1) "File or assembly name XXX, or one of its dependencies was not
found."

- OR -

2) "Could not load the assembly"

Thanks,
Steve Wyatt
