  - Merge "Pass fully qualified anteater path to Docker run"
  - Pass fully qualified anteater path to Docker run

    With moving anteater into a virtualenv inside the container, it is no
    longer installed to a location accessible by the default PATH. Using the
    absolute path to the anteater binary should allow this to run.
