The 32-bit standalone build appears to require two libraries (lib32-libyaml and lib32-gsasl) that are not available on Arch Linux. See the comments on the AUR package. I'd appreciate it if you could bring back the 64-bit build.
done, based on https://aur.archlinux.org/packages/git-annex-bin/ they are managing with what I am providing. Also, Arch Linux has a proper build of git-annex from source, so I'm not going to worry about git-annex-bin, the rationalle for which I don't even understand. --Joey
