Thanks for the confirmation (which I had managed to find from http://www.freebsd.org/cgi/man.cgi?query=tar&apropos=0&sektion=0&manpath=FreeBSD+5.4-RELEASE+and+Ports&format=html ). R does not need xh here, and I have changed it in 2.2.0-beta. I do suggest you submit a bug report on the incorrect error message, though, which should refer to the option used, not one that is not used. -- Brian D.
