Passing pickle between Python and IronPython

I'm having difficulty loading a pickle in Python that was dumped in IronPython.

When I pickle something basic like "[1,2,3]" in IronPython, the pickle loads fine in Python. But, when I pickle results from the DB query below in IronPython, I get the error "No module named clr" when trying to load the pickle in Python.

What might be going wrong? (And is there a better way to share data between Python and IronPython?)

def GetData(id):
    TheConnection = SqlClient.SqlConnection("server=MyServer;database=MyDB;Trusted_Connection=yes")
    TheConnection.Open()
    sqlcommand = "MyStoredProcedure#GetMyData '%s'" %id

    MyAction = SqlClient.SqlCommand(sqlcommand, TheConnection)
    MyReader = MyAction.ExecuteReader()

    results = list()

    while MyReader.Read():
        row = {
               'Type':'LolCat',
               'Date':datetime.datetime(MyReader[1]),
               'Location':str(MyReader[3]),
               'Weight':float(MyReader[6])/float(MyReader[7]),
               }
        results.append(row)

    TheConnection.Close()
    MyReader.Close()

    return results



results1 = GetData(1234)
results2 = GetData(2345)

...
picklefile= open("testpickle","w")
cPickle.dump((results1,results2),picklefile)

...
picklefile = open("testpickle","r")
p = cPickle.load(file)  # this is the line that gives the error "ImportError: No module named clr"
