Actual Results: tar: Read 8646 bytes from /usr/portage/distfiles/arpoison-0.6.tar.gz tar: This does not look like a tar archive tar: Skipping to next header tar: Archive contains obsolescent base-64 headers tar: Error exit delayed from previous errors /usr/lib/portage/bin/ebuild.sh: line 25: cd: /var/tmp/portage/arpoison-0.6/work/arpoison: No such file or directory sed: can't read Makefile: No such file or directory !!!

good I'm glad they fixed that. ebuild is updated.
