Well, Jessie backports policy is to port what is in Stretch (and not a
"random" version).

I do not intend to fiddle around with version 1.4 just to get a fake
version 1.5 be it in contrast to policy or not. In principle when I was
sending my mail I was not (yet) considering it hard and all needed
Build-Depends are just uploaded to backports new queue. I was just
announcing the attempt to backport here as it is considered best
practice.
However, now when really trying to build matplotlib the build ends up
with
...

I: copying local configuration
E: Failed autobuilding of package
I can confirm that the missing file does not exist inside the source
tree:
/build/matplotlib-2.0.0+dfsg1/doc# find . -name "*MarkerStyle*"
/build/matplotlib-2.0.0+dfsg1/doc# grep -R
matplotlib.markers.MarkerStyle.markers
Binary file build/doctrees/api/markers_api.doctree matches
I also have no idea why this warning is treated as error and how to
sensibly build matplotlib.
Any hints?
Kind regards
Andreas.
