Here's the traceback:

Traceback (most recent call last):
   File "ct.py", line 7, in <module>
     class MyEnum(ctypes.c_int, Enum):
   File "/home/ethan/source/enum/enum/py2_enum.py", line 149, in __new__
     enum_class = super(EnumMeta, metacls).__new__(metacls, cls, bases, classdict)
TypeError: Error when calling the metaclass bases
     _ctypes.PyCSimpleType.__new__(MyEnum_meta) is not safe, use type.__new__()

Not sure how to fix that.
