Bugzilla Bug 202838

when installing activesuppot, emerge fails with following message:
 *  The die message:
 *   gem install failed (spec file
/var/tmp/portage/dev-ruby/activesupport-2.0.2/image///usr/lib/ruby/gems/1.8/specifications/activesupport-2.0.2.gemspec
missing)

Reproducible: always

How to fix: delete line 5

platform: ""

from source file activesupport-2.0.2.gem/metadata

(the way gem handle this line to make *.gemspec file slightly different from
ebuild's:

gem - file /usr/lib/ruby/site_ruby/1.8/rubygems/specification.rb, lines
495-501:

    def full_name
      if platform == Gem::Platform::RUBY || platform.nil?
        "#{@name}-#{@version}"
      else
        "#{@name}-#{@version}-#{platform}"
      end 
    end

 *** gem creates file activesupport-2.0.2-.gemspec ***

ebuild - file /usr/portage/eclass/gems.eclass, line51
  spec_path=${D}/${GEMSDIR}/specifications/${P}.gemspec

 *** ebuild looks for file activesupport-2.0.2.gemspec - oops! ***
