Digest fails for me with xerces-c-src_2_7_0.tar.gz, error remains after redownload/sync/manual download.
Hmm, this is really strange since nobody did a redigest or anything else and upstream didn't change the source. Anyway, I committed some minor cleanups today and signed the Manifest, etc. Please wait 1-2 hours, resync, remove /usr/portage/distfiles/xerces-c-src_2_7_0.tar.gz and retry. Reopen the bug if the problem persists, thanks!
http://apache.mirrors.pair.com/xml/xerces-c/source/xerces-c-src_2_7_0.tar.gz Rechecked this, and downloaded from a different server, works now. Obviously this mirror has a faulty file. When I said I manually downloaded the file, I coincidently picked exactly this server again, bad luck...
Sorry, we cannot fix apache mirrors...
