If you email me your sandpile.sage file I could try to figure it out. I made a file with a class definition inheriting from DiGraph and everything tested OK, so I can't reproduce this. The only thing I can think of is that perhaps your command "sage" is calling an older version of sage that doesn't have DiGraphs - ? I don't know the graph theory code well enough to know how likely that is.
