MarsSeed [1] filed a deletion request for gr-ieee802-15-4 [2]: Unused, broken VCS package in disguise. There are no tagged upstream releases since 2013. [a] If someone really needs this on AUR, they can and should create a git VCS package for it. It's not beneficial to keep the current pkgname and PKGBUILD meanwhile.
