ruby and rake version problems

$ ruby --version
ruby 1.9.2p290 (2011-07-09 revision 32553) [i686-linux
$ ls /usr/lib/ruby/
1.9.1  gems  site_ruby
$ ls /usr/lib/ruby/gems/
1.9.1

Why does ruby-1.9.2 use /usr/lib/ruby/1.9.1 and /usr/lib/ruby/gems/1.9.1? Why is there no /usr/lib/ruby/1.9.2 and /usr/lib/ruby/gems/1.9.2?

$ gem list rake

*** LOCAL GEMS ***

rake (0.9.2)
$ rake --version
rake, version 0.8.7
$ /usr/lib/ruby/gems/1.9.1/gems/rake-0.9.2/bin/rake --version
rake, version 0.8.7

wtf?
How can I get rake-0.9.2 to run? I got some issues with Ruby on Rails 3.1.0.

Stupid rubygems (the package system) always seems in conflict with pacman. And no, I don't want to do an "gem update --system" because it could create even more conflicts with pacman.

Re: ruby and rake version problems

Well, we had a similar issue some time ago, and I still recommend that while rubygems and rake are part of the ruby package (in pacman), the package should keep them up to date as well as ruby. Yes, I know the problem is that upstream bundles outdated versions of rubygems and rake with ruby. How do other distributions solve this issue?

Re: ruby and rake version problems

The library paths will remain as 1.9.1 as it indicates the compatibility level (see the 1.9.2 Release Notes).

Rake 0.8.7 is installed as part of Ruby 1.9.2 however Rails 3.1 requires at least 0.9.2.
You can either:  (replaces Rake system-wide and becomes the default version)

gem install rake

or add the newer version of Rake to your Gemfile and use

bundle exec rake

in the root of your Rails app.
