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/config_file.rb:7 from ./lib/rubygems.rb:882:in `require' from ./lib/rubygems.rb:882 from ./setup.rb:22:in `require' from ./setup.rb:22 Some addition config info: [root@home ~]# [root@home ~]# ruby -v ruby 1.8.7 (2008-08-11 patchlevel 72) [i686-linux] [root@home ~]# which ruby /usr/local/bin/ruby [root@home ~]# which gem /usr/bin/gem [root@home ~]# gem -v /usr/lib/ruby/1.8/yaml.rb:14: uninitialized constant YAML::Syck::DefaultLoader (NameError) from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /usr/lib/ruby/site_ruby/1.8/rubygems/config_file.rb:7 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /usr/lib/ruby/site_ruby/1.8/rubygems/gem_runner.rb:8 from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `gem_original_require' from /usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require' from /usr/bin/gem:9 thanks
