I find the destination directory depending on who the user pretends
to be a bit strange, but it works !

Also tested this with a package that includes data files (*.npy)
that should be found by the installed code, and also this works.

The only minor problem is that the sudo version leaves two
directories (build and *.egg-info) that can only be cleaned up
by root. No problem on systems that allow sudo everything, but
I may keep the Makefile just to offer 'sudo make clean', 
assuming most system will allow this. Unless there is a
cleaner solution.
