I have not yet dug into the issue any further. Before doing so I wanted to first check to see if others have successfully built and run via macOS 11.2. If so I would appreciate any pointers. If it is known that it will not yet work, that would be good information
 as well so not to spend anytime digging.

<div class="">I should note that on another machine, I was wiser and upgraded to macOS 10.5.7 (aka Catalina) and built and ran with 3.3.1 that worked fine running in parallel.</div>
