ERROR: Error installing nokogiri: ERROR: Failed to build gem native extension. /usr/bin/ruby extconf.rb install nokogiri checking for #include ... yes checking for #include ... no libxml2 is missing. try 'port install libxml2' or 'yum install libxml2' but when I try and do "yum install libxml2" I get: Package libxml2-2.7.3-1.fc10.i386 already installed and latest version How can I fix this?
