eschwartz [1] filed a deletion request for zfs-utils-common [2]: Duplicate of zfs-utils, most likely created because zfs-utils used to be a split PKGBUILD therefore forcing the binary module packages to makedepend on the dkms package.
The correct solution was to split out zfs-utils, which has now been done. [1] https://aur.archlinux.org/account/eschwartz/ [2] https://aur.archlinux.org/pkgbase/zfs-utils-common/
