Can not install RubyGems (uninitialized constant YAML::Syck::DefaultLoader (NameError))

Hi,

I think I've upset my ruby/gems on my Redhat Linux box (I did an
apt-get install ruby-libs). So I've installed again Ruby from source
(did get some warnings - see previous post), and then tried to install
RubyGem however I get the following error. Any ideas? Anything else
I can post to help?

[root@home rubygems-1.3.1]# ruby ./setup.rb
/usr/lib/ruby/1.8/yaml.rb:14: uninitialized constant
YAML::Syck::DefaultLoader (NameError)
        from ./lib/rubygems/config_file.rb:7:in `require'

        from ./lib/rubygems.rb:882
        from ./setup.rb:22:in `require'
        from ./setup.rb:22

Some addition config info:

PS. I noted I have a few matches for 'ruby'. Not sure if this is
significant re my problem

# find / -name ruby
/usr/local/bin/ruby
/usr/local/lib/ruby
/usr/bin/ruby
/usr/lib/swig1.3/ruby
/usr/lib/ruby
/root/source/redmine-0.7/vendor/plugins/coderay-0.7.6.227/lib/coderay/scanners/ruby

# which ruby
/usr/local/bin/ruby
