Hi, Once again, I don't if it's the appropriate forum to post this question. I have a problem with the dispatch gem on my mac. 1) Problem: $ macirb irb(main):001:0> require 'dispatch' LoadError: no such file to load -- dispatch 2) My configuration: --> MacBook Pro, 2.5 GHz Intel Core 2 Duo (yes, an old one. Since Christmas is close and you would like to give me a gift .... :) ) --> Snow Leopard 10.6.8 64 bits on ( In system information: Noyau et extensions 64 bits : Oui) --> $ macruby -v MacRuby 0.10 (ruby 1.9.2) [universal-darwin10.0, x86_64] --> $ macgem query --local *** LOCAL GEMS *** dispatch (0.0.1) mspec (1.5.17) Thanks a lot for reply François PS: Is there a forum for beginner questions like mine, because I do not want to bother you with these basic questions
