Bug#986577: bouncy: Fails to run without missing dependency python3-future

[Hans Joachim Desserud]

Package: bouncy
Version: 0.6.20071104-7
Severity: important

Dear Maintainer,

bouncy curently fails to run with the following error message:

$ bouncy
pygame 1.9.6
Hello from the pygame community. https://www.pygame.org/contribute.html
Traceback (most recent call last):
   File "/usr/share/games/bouncy/game.py", line 18, in <module>
     from map import *
   File "/usr/share/games/bouncy/map.py", line 7, in <module>
     import euclid, collide, objects, pyglyph, fonts
   File "/usr/share/games/bouncy/euclid.py", line 36, in <module>
     from past.builtins import long
ModuleNotFoundError: No module named 'past'

After installing python3-future, it seems to run as expected. I assume
this should be added as a package dependency.

The import in question seems to have been introduced by the Python3 
patch
