www/ddgr and www/py-ddgr both install the same project, they were even created one day apart. www/ddgr is the most up-to-date so www/py-ddgr should be removed. There doesn't appear to be any python module installed so the py- prefix seems unnecessary.
^Triage: MAINTAINER of ddgr is a committer, assign accordingly ddgr is registered in PyPI, py-ddgr is the correct name on that basis (degree of 'moduleness' is not). @Dmitry Could you merge/move www/ddgr into www/py-ddgr please
