build failure: no method named `normalize` found for struct `pbtime::Timestamp` in the current scope

I'm getting the following error trying to include prost-wkt-types as a dependency:

error[E0599]: no method named `normalize` found for struct `pbtime::Timestamp` in the current scope

Can you include your Cargo.toml and build.rs so I can try to replicate the problem?

[tarcieri]

I pushed up a branch where I'm experiencing this problem:

https://github.com/informalsystems/tendermint-rs/tree/tarcieri/prost-wkt-types

It can be reproduced with:

$ cd proto
$ cargo build

In the Cargo.toml I see that default-features is set to false. This means std is not used, which means the normalize function is not available. Unfortunately this implementation comes straight from Prost, so its not in Prost-wkt-types. Luckily, though, the master branch of Prost seems to have already addressed this (see commit 1674ef9). I'll see if I can update Prost to the latest version of Prost for the next release of prost-wkt.
