Following Martin v Löwis's suggestion, I looked at

 http://bugs.python.org/issue1358

and added the line
#define	SETPGRP_HAVE_ARG
by hand to pyconfig.h  (after it was created by configure).  Then
6. run  "make"
7. run "make test"  (one test failed; this step likely unnecessary)
8. sudo make altinstall
9. sudo ln /usr/local/bin/py3k/python3.0 /usr/bin/python3.0

10. type "python"
11. print("Hello world!")
12. Be happy!

André, hoping this report might help some other newbie.
