As Julien noted, you need to have thrift 0.7.0 installed. You also need 
protoc 2.5.0 installed for protobuf. I'll add more information in the 
README for this.

In the mean time, if you take a look at the .travis.yml file, you can 
see the preparation steps used to run CI jobs. That's what I usually 
point people at instead of maintaining it in two places, but I agree 
that shouldn't be the solution.

Thanks for taking a look at this!
