on a newly installed system with only python 3.2.2, tried to install app-backup/duplicity-0.6.18-r1 which eventually depends on dev-python/pexpect. but dev-python/pexpect does not depend on python so the merge fails due to the wrong order: # emerge -av duplicity These are the packages that would be merged, in order: Calculating dependencies... done!
