Ruby's flagship gem, rails, no longer installs on a vanilla gentoo machine which has ruby and rubygems. See details: https://github.com/rails/rails/issues/4565 Basically, the current stable rubygems 1.3.7 crashes while installing recently-packaged gems. If there's no reason not to, perhaps it's due time to unmask 1.8.x ebuilds Reproducible: Always Steps to Reproduce: 1.gem install rails 2. 3. Actual Results: ERROR: While executing gem ... (NoMethodError) undefined method `call' for nil:NilClass Expected Results: Rails and dependency gems to be installed successfully
Looks like the Rails people consider this a bug on their end. In any case we can't currently mark newer versions of rubygems stable until all use of the gems.eclass has been removed from the tree. We are almost there, but so far it hasn't been a priority.
