On amd64: The stable package virtual/krb5-0-r1 depends on unstable app-crypt/heimdal-1.5.3-r2 This is causing major confusion with extremely cryptic blockers when you are using heimdal and try to upgrade virtual/krb5 because other packages need it. Either you need to remove amd64 keyword from virtual/krb5-0-r1 or set the amd64 keyword on app-crypt/heimdal-1.5.3-r2 Reproducible: Always Steps to Reproduce: Have virtual/krb5-0 and app-crypt/heimdal-1.5.3 installed. emerge --sync emerge -uDNvp virtual/krb5
