SpotlightKid [1] filed a orphan request for capnproto-git [2]: Current PKGBUILD doesn't build but maintainer hasn't fixed it. Maintainer doesn't react to comments or issues in his own Github repo issue tracker, the URL of which is given in the PKGBUILD as the place to report problems with the package. https://github.com/SShrike/pkgbuilds/issues/2 [1] https://aur.archlinux.org/account/SpotlightKid/ [2] https://aur.archlinux.org/pkgbase/capnproto-git/
