Description:

While trying to use pacman-installed Ruby gems with Bundler (ruby-bundler, from AUR), it can't find the gems that are installed under /usr/lib/ruby/vendor_ruby/RUBYVERSION (including polyglot, mail, mime-types, and treetop). Since this is a packaged Gem, and since it installs a specification to /usr/lib/ruby/gems/RUBYVERSION/specifications, I believe its contents should be under /usr/lib/ruby/gems/RUBYVERSION/gems and not under /usr/lib/ruby/vendor_ruby/RUBYVERSION; and I don't believe this is a Bundler issue, even though it's Bundler that's complaining as below. I've filed this bug against ruby-polyglot, since that appears to be the one on which the others depend, but the problem also appears to exist in those packages as well. If you'd like me to file separate bug reports for them I'd be happy to do so, and please let me know if I've left anything out or filled in anything incorrectly, as this is my first Arch Linux bug report.

Additional info:
* ruby-bundler-1.5.2-1 (from AUR)
* ruby-polyglot-0.3.3-2

Steps to reproduce:
1. Install ruby-bundler from AUR, and ruby-polyglot from community.
2. Create a file named "Gemfile" in an empty directory containing only the line: gem 'polyglot'
3. Run: bundle show polyglot
4. Output:

The gem polyglot has been deleted. It was installed at:
/usr/lib/ruby/gems/2.0.0/gems/polyglot-0.3.3

which is due to Bundler finding the gemspec at the expected location, but not the gem's contents, as those are under vendor_ruby.
