umm.  why would you ever need to do that?

>>> dir(__builtins__)
['ArithmeticError', ...]
>>> import exceptions
>>> dir(exceptions)
['ArithmeticError', ...]
>>> for name in dir(exceptions):
...     if getattr(__builtins__, name, None) == None:
...             print name, "is missing"
...

and if you don't want to, you don't have to inherit from the
Exception class either.  the difference between

    MyException = "MyException"

and

    class MyException: pass

isn't really that big...
