scala error:: Scala library in Project Structure -> Libraries has red square on it

I am switching to a new mac.  The code in question builds with no errors in IntelliJ on my old box.

I get the following error when trying to build a newly dowloaded "master" project from our repository.

error: scala.reflect.internal.MissingRequirementError: object java.lang.Object in compiler mirror not found.

When I look in the Project Structure -> Libraries folder I see that a scala library had a small red box on it (see screenshot) 

What does the red box mean?  How could I resolve this?  The file in question appears to be available based on the other panes in the "Libraries" window.  The Library that has a "red square" on my new box has no such thing on my old box where everything builds correctly.
