Running "rdflib.Graph('LevelDB')" gave the error:

File "rdflib_leveldb/picklr.pyx", line 2, in init rdflib_leveldb.picklr (rdflib_leveldb/picklr.c:2037)
ImportError: cannot import name GraphValue
So I went to picklr.pyx and removed all references to GraphValue, since the class is obsolete. I then reran the command, and got this long traceback:
