When I find portage is unable to resolve the graph of packages for an update, I add a high number for backtrack. You've already done this: "(backtrack: 0/200)". Then I typically try to update portage: emerge -1auNDv sys-apps/portage or if there are no new USE flags affecting it, emerge -1aDv sys-apps/portage This should sort out portage and its latest python dependencies as a start. Then I check if the graph can be resolved. If not, I start with updating one or just a few of the top packages in the list at a time. After updating perl, run: perl-cleaner --reallyall to rebuild any broken packages. Finally, if there is just one or two blockers I mask them or more often I temporarily uninstall them until the rest of the packages have been brought up to date. The above not particularly scientific approach has worked on my systems many a time, but YMMV.
