The error clearly says unknown argument '-fuse-ld=mold' which means mold linker is not properly installed or configured for your clang++. Anyhow, I don't think this belongs to the scope of this project.

Assuming the same user, problem was caused by settings that were incompatible with the AUR package. Package has been revised, and the error should no longer occur.

Feel free to @ me for any issue that appears to be related to the AUR package. (eg, .cache/yay in the error message)
