bsdtar fails on xorg-libraries (X11R6.7.0-src3.tar.gz)

When attempting to reinstall xorg-libraries with -CURRENT from today 
(using WITH_BSDTAR), I ran across a problem extracting 
X11R6.7.0-src3.tar.gz:

$ bsdtar xf /usr/ports/distfiles/xorg/X11R6.7.0-src3.tar.gz
xc/programs/Xserver/: Can't set permissions: No such file or directory
xc/programs/Xserver/GL/: Can't set permissions: No such file or directory
xc/programs/Xserver/GL/apple/: Can't set permissions: No such file or 
directory
$ echo $?
1
$ rm -rf *
$ gtar zxf /usr/ports/distfiles/xorg/X11R6.7.0-src3.tar.gz
$ echo $?
0

I had successfully upgraded xorg-libraries after the last commit (some 
34 hours ago), so the issue is most likely with the "fourth complete 
rewrite of the dir-creation code":
http://lists.freebsd.org/pipermail/cvs-src/2004-July/026963.html

Just FYI: I was reinstalling xorg-libraries because I forgot that our 
in-tree gcc produces a broken (xfree86|xorg)-libraries with -Os as seen 
before on this list.
