Failed to build django-rest-elasticsearch
Installing collected packages: Django, djangorestframework, six, urllib3, elasticsearch, python-dateutil, elasticsearch-dsl, django-rest-elasticsearch

The LICENSE file (which is yet present in the repository) seems to be missing... and indeed when I looked in to the tar.gz archive on pipy, it is not included in the package.
Can you help me figure this out please ?
