Ah yes, the Makefile assumes that "python" is Python 3, which
unfortunately isn't true for most distros. I fixed that now, but you can
also already override the python binary used by the Makefile:

sudo make PYTHON=python3 install

Good, that means you have all the run-time dependencies installed.
setuptools is just needed when you want to install jack-select via the
Makefile (which runs "python setup.py install" to install the jackselect
Python package).

Yes, because it uses "from jackselect.jackcontrol import ...", so the
"jackselect" Python package has to be either installed in the
system-wide Python module path or be available in the current working
directory where you start the script.

No.

Yes, relative to the file that uses this form of importing. This only
works within Python packages, though. Thatswhy in my example I used
"from jackselect.jackcontrol import ..." (without the leading dot). See
here for an explanation:

https://docs.python.org/2.5/whatsnew/pep-328.html

But you could also just take the "jackcontrol.py" file, and put it next
to your application's main script and then just use "from jackcontrol
import ...".
