tar: Error exit delayed from previous errors.

[lhmwzy]

I use tar to extract a tar.gz file which created under FreeBSD 7.2 with
bsdtar 2.5.5.
But under DF,tar xzvf this file,last give me a error:
tar: Error exit delayed from previous errors.

uname -a:
DragonFly bxzx 3.8-RELEASE DragonFly v3.8.2-RELEASE #3: Thu Aug 21 07:20:47
CST 2014     lhm at bxzx:/usr/obj/usr/src/sys/lhmwzy  x86_64

Is this a bug?
