As a side note, please don't use something like "sys-apps/portage-2.1_pre9-r4 and etc-update" as a summary. A summary shouldn't be just the name of the components where the problem exists. It should be a _description_ of the problem. Also, you should always post your "emerge --info" output. Please read the bug posting FAQ before posting bug reports.
