I can not update system because: emerge --update will install dev-lang/ruby-1.8.6-r1 but dev-ruby/rake - need dev-lang/ruby-1.8.5_p2-r1 It can not be istall both of them. Mayby solved - please verify my solution. Reproducible: Always Steps to Reproduce: 1.dev-lang/ruby, dev-ruby/rails and dev-ruby/rake muss be istalled 2.emerge --deep --newuse --update world 3. Actual Results: update succesfull Expected Results: depedecies conflict When I try update my system by emerge --deep --newuse --update world I have got this screen: ==BEGIN_SCREEN== Calculating world dependencies / !!! Multiple versions within a single package slot have been !!! pulled into the dependency graph: ('installed', '/', 'dev-lang/ruby-1.8.5_p2-r1', 'nomerge') pulled in by ('installed', '/', 'dev-ruby/rake-0.7.1', 'nomerge') ('ebuild', '/', 'dev-lang/ruby-1.8.6-r1', 'merge') pulled in by ('installed', '/', 'dev-ruby/rake-0.7.1', 'nomerge') ('installed', '/', 'dev-ruby/ruby-config-0.3.1', 'nomerge') It may be possible to solve this problem by using package.mask to prevent one of those packages from being selected. 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. For more information, see MASKED PACKAGES section in the emerge man page or refer to the Gentoo Handbook. !!!

You are correct: your solution is not a good solution, and it also does not work, at least not for everyone. The specific problem with it is noted in the ChangeLog. The right solution is that we stable a later version of rake now that ruby 1.8.6 is going stable, as mentioned in bug 181110. Looking at the tree both rake-0.7.3 and ruby-1.8.6-r1 are now stable for x86, so your problem should be fixed after another emerge --sync.
