Are you sure that the build isn't being performed as root?  There could be a
configuration error of some sort.  Try adding

  preConfigure = "id; exit 1";

to the GNU tar builder and do "nix-build -A gnutar".  It should print something like

  uid=30001 gid=30000

(or whatever the uid/gid is of the Nix build users).
