ImportError: No module named '_pandasujson'

As I mentioned in #80, a change introduced after 0.2.2 breaks a previously working serialized function call that relied on importing pandas. My suspicion is that serialization of functions that utilize pandas may be broken in recent versions of cloudpickle.

Full backtrace from Dask/prep.py:

Let me know if I can help dig further into this!

It's been a while now, but does the error still appear?
