Obvious typo in the manpage (should be --membind node:0), I am fixing this.

You get the same error when running only "hwloc-bind --get --membind",

I am not sure about this one. Do you have NUMA support in your kernel?
Is your machine NUMA? Can you send the gather-topology tarball ? (if we
don't have it already :))

Oops, I removed it by mistake, fixing this too.
