@craigcitro gcloud-python is going to have to pin to 0.10.0 until this issue is resolved.

[craigcitro]

so I have a PR out on apitools (google/apitools#54) to update to using the new naming; I forgot that I didn't have protorpc pinned in apitools.

i'll also just add a temporary alias on the protorpc side, on the off chance this breaks anyone else.

New release is out, you should be good to go.

Thanks for the quick turnaround!
