amatwkgs [1] filed a orphan request for fatrat-git [2]: With boost 1.66 (and above), the package will not build and the upstream has created another branch (https://github.com/LubosD/fatrat/tree/feature/poconet_migration) to solve the problem. A comment was left 2 weeks ago to notify the maintainer so that the PKGBUILD can be updated, but the maintainer is MIA.
