python2-pyglet bundles a future module, but hacks the sys.path to get it done
this crashes brainworkshop who's relying on the proper definition of sys.path (see code below)
by simply depending on python2-future we avoid this hackish behavior
the python3 package does not have this problem as future is a native module



# Check if future is installed, if not use included batteries
try:
import future
except ImportError:
import os.path as op
import sys
future_base = op.abspath(op.join(op.dirname(__file__), 'extlibs', 'future'))
sys.path.insert(0, op.join(future_base, 'py2_3'))
if sys.version_info[:2] < (3, 0):
sys.path.insert(0, op.join(future_base, 'py2'))
del future_base
del sys
del op
try:
import future
except ImportError:
print('Failed to get python-future')
raise
