Subject: Problems installing rails on OSX

Help out a poor dumb Pythonista who's trying to give rails a try.

I'm running OSX 10.3.9.  I followed the directions at http://www.rubyonrails.org/down and 
installed from source ruby 1.8.4.  OSX came with ruby 1.6.8 pre-installed in /usr/bin.  I 
moved that to /usr/bin/ruby-1.6.8 and make /usr/bin/ruby a symlink to /usr/local/bin/ruby.  
All of this went well:

Roy-Smiths-Computer:rubygems-0.9.0$ ruby --version 
ruby 1.8.4 (2005-12-24) [powerpc-darwin7.9.0]

Then I downloaded RubyGems, which went not so well:

Roy-Smiths-Computer:rubygems-0.9.0$ gem --version
/usr/local/lib/ruby/site_ruby/1.8/rubygems/cmd_manager.rb:52:in `initialize': 
uninitialized constant Gem::CommandManager::HelpCommand (NameError)
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems/cmd_manager.rb:46:in `instance'
        from /usr/local/lib/ruby/site_ruby/1.8/rubygems/gem_runner.rb:25:in `run'
        from /usr/local/bin/gem:23

Any hints what I might have done wrong, or where to start looking?
