Error: could not insert module /lib/modules/3.16.0-0.bpo.4-amd64/updates/dkms/zfs.ko: Unknown symbol in module
Looks like you weren't paying attention. SPL was probably not built (correctly).
What should have alerted me? This is what was printed during installation for the spl installation and after (I don't see anything wrong apart from the "sh: 1: .: : not found" bit):

… and this.
Is there any other information that could be helpful for me to supply? I tried various combinations of rebooting using the 3.2 kernel, purging and reinstalling 3.16, rebooting using 3.16, purging and reinstalling zfs, but that didn't get me anywhere.

I honestly have no idea where that symbol comes from. It's not in spl, zfs nor in my 3.2.0 kernel sources.
But it seems to be a problem with your kernel. I found this when googling a little:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=779922
If you follow the links to the other issues about this, they don't seem to know what to do with that.
Thank you, that convinced me to try again downgrading to 3.2. In case it helps anyone, here's what I did to recover. I am not offering any guarantees this is the correct (nevermind optimal) thing to do or that doing this won't leave your system unbootable: -purged dracut, linux-image-3.16, all packages with "zfs" in the name -downgraded grub-efi (was at "grub-efi 2.02-beta2.9-ZOL10-7aa9f6-wheezy" -- for some reason the first update I did for zfs also installed several beta ZOL packages) and initramfs-tools: aptitude install initramfs-tools=0.109.1 aptitude install grub-efi=1.99-27+deb7u2 (also needed to run "update-initramfs -u -t -k 3.2.0-4-amd64") -reboot -purge spl spl-dkms apt-get install debian-zfs zpool import -d /dev/disk/by-id Everything seems fine now. Closing.
I installed the new zfs 0.6.4, and after reboot I got:
zpool status
