This problem was brought to my attention by Brian Harring when he notices fetch failures for app-emulation/emul-linux-x86-xlibs-7.0-r1: http://dev.gentoo.org/~zmedico/infra/distfiles/failure.xml There was a bug in portage (now fixed) that caused of of the MD5 digests to be discarded in this commit: http://www.gentoo.org/cgi-bin/viewcvs.cgi/app-emulation/emul-linux-x86-xlibs/files/digest-emul-linux-x86-xlibs-7.0-r1?hideattic=1&r1=1.2&r2=1.3
Note to self: a portage upgrade will fix this issue.
We've got portage-2.1 on osprey now, so this is fixed.
