'emerge -pvuNDt world' does not want to something with vlc, but if I want to install something else, emerge tries to downgrade vlc to 2.1.5-r1, e.g. root@impala:/usr/src/linux(51)# emerge -pvuNDt qalculate-gtk These are the packages that would be merged, in reverse order: Calculating dependencies... done!
