build command doesn't seem to find local images

[hjwp]

To repro:

Build and tag an image locally:

mkdir test1
echo 'FROM ubuntu' >> test1/Dockerfile
echo 'RUN touch /etc/i_was_here' >> test1/Dockerfile
docker build -t me/my_new_image test1

Now let's create a dockerfile that builds from this new local image:

mkdir test2
echo 'FROM me/my_new_image' >> test2/Dockerfile
echo 'RUN touch /etc/i_was_here_too' >> test2/Dockerfile

Confirm it works:

docker build test2
Step 0 : FROM me/my_new_image
 ---> 0f31d2454ece
Step 1 : RUN touch /etc/i_was_here_too
 ---> Running in 890853da77b8
 ---> 0a0ffa637067
Removing intermediate container 890853da77b8
Successfully built 0a0ffa637067

Now try it using the docker-py build command:

python -c'from docker import Client; docker = Client(base_url="unix://var/run/docker.sock"); output = docker.build(path="/tmp/test2"); print("\n".join(output))'

gives

{"stream":"Step 0 : FROM me/my_new_image\n"}
{"status":"Pulling repository me/my_new_image"}
{"errorDetail":{"message":"Error: image me/my_new_image:latest not found"},"error":"Error: image me/my_new_image:latest not found"}

So it seems like, when run through docker-py, the build command isn't finding the local image??
