I first noticed that while upgrading dev-ruby/sqlite3: * Running compile phase for all ... rake aborted! Gem::ConflictError: Unable to activate hoe-3.14.1, because rake-11.2.2 conflicts with rake (< 11.0, >= 0.8) But I can reproduce this on the command line as well: $ sow --help /usr/lib64/ruby/site_ruby/2.2.0/rubygems/dependency.rb:310:in `to_specs': Could not find 'rake' (< 11.0, >= 0.8) - did find: [rake-11.2.2] (Gem::MissingSpecVersionError) I suggest editing the ebuild for hoe-3.14.1 so it expresses this dependency as part of its RDEPEND setting. https://rubygems.org/gems/hoe suggests that the lates version of hoe is 3.15.2 which depends on rake < 12.0, so a bump to that package would allow people to use hoe with the latest version of rake.
Thanks for the report. I have now added the upper bound dependency to hoe 3.14.1. Newer hoe versions had not been added yet due to test failures. I have now investigated these and as a result hoe 3.15.2 is now also in the tree.
