It would be nice to have an ebuild for the host application required for browserpass. An Arch Linux PKGBUILD file is available and could be used as a basis for an ebuild: https://aur.archlinux.org/cgit/aur.git/tree/PKGBUILD?h=browserpass DESCRIPTION="Host application for Chrome & Firefox browser extension for pass, a UNIX password manager" HOMEPAGE="https://github.com/dannyvankooten/browserpass"
This one was added to gentoo recently. https://github.com/gentoo/gentoo/pull/5836
