Where to put dll's in starkits

When creating a starkit, there is a specific hierarchy to follow with the vfs folder.  For example, you put your packages in "lib".
However, some packages have dll components that normally reside in the bin folder of your Tcl/Tk installation. How do you handle these dll files?  Where do they go?  Is there a way to ask the starkit to check a certain place for any dll's it may need?
