To build the image:

$ docker build \
>   --file get-pip.Dockerfile \
>   --tag dhermes/repro-4352:latest \
>   .

After building and running the shell, the import succeeds:

$ docker run \
>   --rm \
>   --tty \
>   --interactive \

To build the other image, which uses requirements.txt and installs pip via apt-get:

$ docker build \
>   --file apt-get.Dockerfile \
>   --tag zafields/repro-4352:latest \
>   .

After building, running:

$ docker run \
>   --rm \
>   --tty \
>   --interactive \
>   zafields/repro-4352:latest \
>   /bin/bash
