I have a partial answer as to what is causing these errors. Before starting 'make' I switched to the Sage directory using 'cd desktop/sage', as you can see by the small 'd' in 'desktop'. On a Mac that directory is most properly 'Desktop' with a capital 'D'. I revisited the build that halted by switching to the Sage directory with 'cd Desktop/sage' and again running 'make', and now everything copies and builds just fine.
That leaves open the question of why the build process is allowed to mostly work with the slightly wrong directory name, and how to flag the error before building starts.
