racc/parser.rb not found in gem

Hi,

first off, I'm new to both ruby and rails.

I just installed ruby 1.9.2 on gentoo, then rails-3.0.0 as a gem (with --user-install).

Following http://edgeguides.rubyonrails.org/getting_started.html, Step 4.1 "Starting up the Web Server" failed:

$ rails server
=> Booting WEBrick
=> Rails 3.0.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
Exiting
/home/.../.gem/ruby/1.9.1/gems/activesupport-3.0.0/lib/active_support/dependencies.rb:239:in require': no such file to load -- racc/parser.rb (LoadError)

... stack trace

Installing racc as a gem (--user-install again) didn't fix this.

It appears my ruby install has no racc, so I copied racc.rb and racc/parser.rb from the gem to /usr/lib/ruby/1.9.1, which fixed the problem.

But wouldn't it be better if racc/parser.rb could be found in a gem too, or even if a dependency to the racc gem were added?
