Due to upstream released packege corrections under the same filename, distfiles.gentoo.org contains improper version of some files (net-zope/zope). I kindly ask to remove from distfiles files named: Zope-2.9.7-final.tgz Zope-2.10.3-final.tgz and then let them be refetched from the upstream in the normal fashion. If some actions is needed by me, or I can do it by hand in some way, please let me know.
Solving bug, due to the commits with corrected checksums of zope were maid by me. As ferringb explained to me, this is the only action needed to mirroring tier pick up the files automatically. I'll reopen the bug in case of problems.
