well, never used zfs, but if it's about building the kernel module,
I've done the procedure for maybe a decade:

You need to install the header package for your kernel; the version
of the kernel package and the heaers package need to match exactly
(including the debian revision digit), or the module build will fail.

zfs is in contrib section so make sure you have enable it in apt sources;
then intall (or reinstall or remove and install) zfs-dkms package, it
should trigger
the build of the module.
To mount the zfs home you probably need other tools from the linux-zfs source,
not sure which one, maybe zfsutils-linux, I don't know for sure. See
the complete list in
https://packages.debian.org/source/bookworm/zfs-linux
(yes its a Debian link but I think Devuan does not fork those packages)

Best,
Lorenzo
