Request #41565 has been Rejected by MarsSeed [1]: Revoking as there is a new situation regarding this package.
Its companion 64-bit library has been removed from Arch, without it being added to AUR. The 32-bit library is unlikely to be used, though. I've left comments about it on AUR page. It is best to give time for discussions on the best course of action. [1] https://aur.archlinux.org/account/MarsSeed/
