I'd like to use py-django-haystack django 2.0 but the port is hardwared to use 1.11 (via a RUN_DEPENDS on www/py-django111). Here's a patch that changes the dependency from the specific version to the py-django metaport. This lets uses pick the django version via py-django options.

It sounds like using the py-django metaport is not preferred.
