Heh, I was a bit tired last night, so although I knew that
I required python to be installed to run the test-suite, I
could not remember why. As soon as I went to bed, ... :)
I recently installed Ubuntu 18.04, so that I could get a heads
up on any possible problems later this month when I install
Linux Mint 19. In order to get the test-suite to run, I had
to set 'PYTHON_PATH = /usr/bin/python3' in my config.mak file.
(yes, I could have set NO_PYTHON, but you get the idea).
Ubuntu 18.04 no longer installs python2 by default (it has
ported to python3), but presumably you can still install it
as '/usr/bin/python' (I didn't check).
In any event, it was t9020-remote-svn.sh that was failing
which, despite the name, does not depend on 'svn'. As you
already noted, it does run svnrdump_sim.py and the git-remote-testsvn.

Agreed. And I see it has come to pass ... :-D
