I assume that your OS in Windows — shell is Windows only.  Fortunately, it appears that the changing “shell” to “system” works in OS X.
So, now I have a solution for both OSs.  

This issue was a prelude to a larger issue that I will address in a separate email.

Thanks to everyone for their suggestions.
