>Description:
	pax/tar ignore filenames that contain `..' as a path component.
	(It's OK. Very secure.)

	And ignore symlinks that contain `..' in symlink target, too!
	(It's WRONG!, isn't it?)

	e.g.) cdrtools-1.10.tar.gz (pkgsrc/sysutils/cdrecord)
	  :
	lrwxrwxrwx joerg/bs          0 Jul 21 22:35 2000 cdrtools-1.10/inc/getfp.c -> ../lib/getfp.c
	  :
	This symlink is ignored. Of course, make package is always fail.

>How-To-Repeat:
	See Description.
>Fix:
	I don't know. Please fix this bug ASAP!
