!!! Digest verification Failed: !!! /usr/portage/distfiles/gmp-4.1.4.tar.bz2 !!! Reason: Failed on MD5 verification failing mirrors (so far): http://gentoo.osuosl.org/distfiles/gmp-4.1.4.tar.bz2 ftp://ftp.citylink.co.nz/gentoo/distfiles/gmp-4.1.4.tar.bz2 ftp://ftp.ring.gr.jp/pub/GNU/gmp/gmp-4.1.4.tar.bz2 I stopped checking mirrors after 3 found to be bad MD5.
also fails on http://distfiles.gentoo.org/distfiles/gmp-4.1.4.tar.bz2
Looks like it was just rsync in a race condition. I tested couple of those mirrors below and all checked out. It probably just fixed itself on the next subsequent sync.
