AEM 6 - Sightly Page Component + Inheritance

Good morning.
We have a base page component written using sightly, with a sling:resourceSuperType of "wcm/foundation/components/page".  We then have another page component, let's just call it "page_component" that has a sling:resourceSuperType which is the base page component.  When i create a page with the base page component, everything works correctly, however, when I create a page using the "page_component", I get the following error:

"Caused by: io.sightly.java.api.SightlyUseException: Required script resource could not be located: head.js"

Obviously the entire error is longer, but that's the important line.   With page components previously, the inheritance of files would go back to the ootb component.  That doesn't seem to be the case with sightly and the use of javascript files.  Is this the intended behavior and i need to create a local head.js file, or is there an extra step that needs to be taken with a sightly page component?

Thanks in advance.
