Oh, yeah I see that now it uses both. I sent a report to the tar group,
maybe its something they can fix. I got that error when both unpacking the
source tarball and within the doc directory.

Everything seems to work fine by hand, chown, chgrp, etc..Maybe its a system
call issue with tar, though it all worked fine in NFSv3 which does not use
an ID mapper daemon. I guess not too many people are using NFSv4 (I had to
specify nfs4 in fstab, its turned off by default in Ubuntu 9.04 jaunty).
Maybe I should go back to 3...

The only downside with adding o to tar that I can see is if it isn't
supported by a non-GNU version of tar.
