This may not be helpful, but numpy is pretty helpful for this sort of thing:

import numpy
import numpy.random

a=numpy.random.randint(1,6,50000000)
b=numpy.random.randint(1,6,50000000)

numpy.bincount(a+b-1)

array([      0, 1999229, 4000369, 5999372, 7999232, 9998769, 8003430,
       5998538, 4001160, 1999901])

This takes a few seconds on my system.
