no automatic upgrade of packages build with old dev-lang/go have to _manually_ emerge them Reproducible: Always Steps to Reproduce: 1. emerge new dev-lang/go 2. emerge world --with-bdeps y --verbose-conflicts 3. watch for old dev-lang/go binaries reported Actual Results: sudo emerge -auvDN world --with-bdeps y --verbose-conflicts Password: These are the packages that would be merged, in order: Calculating dependencies... done!

However, it is also possible that conflicting dependencies exist such that they are impossible to satisfy simultaneously. If such a conflict exists in the dependencies of two different packages, then those packages can not be installed simultaneously. You may want to try a larger value of the --backtrack option, such as --backtrack=30, in order to see if that will solve this conflict automatically. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. Expected Results: sudo emerge -auvDN world --with-bdeps y --verbose-conflicts These are the packages that would be merged, in order: Calculating dependencies... done! Total: 0 packages, Size of downloads: 0 KiB Nothing to merge; quitting. To get out of this: emerge all reported packages compiled with non-actual dev-lang/go here:sudo emerge -1 app-emulation/containerd dev-go/go-text dev-go/go-tools dev-go/go-net dev-go/sanitized-anchor-name dev-go/go-md2man app-emulation/runc dev-go/blackfriday then again emerge for world with bdeps: OK .. see 'Expected Results' above!
If you can still reproduce it then please attach a debug log created as follows: emerge -puvDN world --with-bdeps y --verbose-conflicts --debug > debug.log 2>&1
not reproducible! dependencies are now rebuild without fuzz. --> RESOLVED i did: fallback to dev-lang/go-1.6.3 emerge all dependent packages (emerge -1 app-emulation/containerd ...) back to dev-lang/go-1.7 no problems any more using -with-bdeps y the only difference i see is that app-emulation/containerd now is forced to (~)0.2.3 (runC, docker) maybe fishy but gone: app-emulation/containerd-0.2.2_p20160622:0/0::gentoo anyway... if that happens again i will do the --debug! cu kind regards Wolfgang
I am closing this per the last comment.
