MarsSeed [1] filed a deletion request for rdkit-git [2]: Useless, dead-on-arrival resubmit on 2023-05-24 of the 2016 version of this package. Has been deleted once (PRQ#30331). (There are some comments from 2016, but they have come from another package that got merged into this one. This package has 0 "native" comments, also no votes, and its popularity is 0.000000.) Maintainer seems MIA since last year. Package lacks the mandatory conflicts entry. Not beneficial to keep on AUR in my view. Upstream is actively developed and they create frequent release tags. There is a maintained AUR/rdkit that provides the latest version. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/rdkit-git/
