Hi there, sorry for the n00b question: What's the correct linux command for upgrading ruby to a specific version? (Ruby 1.8.6-p369 is needed.) Btw, it's this security issue that leads me to it: http://www.ruby-lang.org/en/news/2009/06/09/dos-vulnerability-in-bigdecimal/ Thanks a lot! Tom -- Posted via http://www.ruby-forum.com/.
