Yes, thanks. What failed was the invocation of PIPE. Apparently I had to
explicitly import PIPE from subprocess or python had no clue as to what PIPE

Dare I say, "wtf?" since when fo I have to specify such? Shouldn't importing
the subprocess module make all its methods available? I can't remember having
to do this before.

The test of a first-rate intelligence is the ability to hold two opposed ideas
in the mind at the same time, and still retain the ability to function.
