Athemis [1] filed a orphan request for ucsf-chimera [2]: New stable release since 10/2017, current PKGBUILD produces non- functional package (incompatible libraries shipped with original binary tarball). Current maintainer has not responded to comments nor updated the package since 2016. [1] https://aur.archlinux.org/account/Athemis/ [2] https://aur.archlinux.org/pkgbase/ucsf-chimera/
