Try a Python program that contains only a single line:
import threading
Of course, it does nothing useful, and should just return without doing or
printing anything.
On Python 2.6.5, on both Windows 2000 and Ubuntu Linux 10.04, if I make an
executable with cx_Freeze
4.1.2, when I run it I get the error message as described above.
