What did work was this from Terminal…

rm -r /Users/mjh/Library/R/3.4/library

apparently eliminating it from .libPaths with this…
paths <- paths[dir.exists(paths)]
?

I had tried removing everything from the directory at one point but then I did 
a mkdir for the directory itself thinking it would do no harm at least having 
it there.
But apparently it can be a problem if it even exists it then seems to become 
the default period?

My guess is that you are running the R.app GUI and have not unchecked the 
default settings in the Startup panel of Preferences:

Sorry. Make that:

.libPaths("/Library/Frameworks/R.framework/Versions/3.4/Resources/library")
