Julian, it appears you already have gem installed, so you don't need to compile it from source. What you are missing though is a zlib library. What you need to do is cd into your ruby 1.9.2 source code dir then into ext/zlib (so for me it'd look like /home/username/Desktop/ruby-1.9.2-p0/ext/zlib/). Then run: ruby extconf.rb make make install Then you should be able to run gem install rails Hope that helps. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
