I don't see that? (that is, I downloaded the Arduino IDE and there's no
file called bossa* there at all).

What I did do is look again at https://github.com/shumatech/BOSSA.git
and **check out the 'arduino' branch** (and compile with clang, not
GCC!)

If I leave out -U and -p this works (after a long pause while it scans
through /dev/cu.Bluetooth- devices before finding /dev/cu.usbmodem1411
(this seems stable for the Due programming port on the USB port nearer
the front of the Macbook)).

Now I have to find out why I'm getting 'Floating point exception: 8",
but this is a huge improvement!
