I'm trying to get macirb that came with my new MacRuby installation to play nice ly with the existing .irbrc, where I'm using a lot of gems previously installed with gem. It looks like my gems aren't found by macirb because they were install ed with gem, so are not found / used by macgem. Would I really need to install a ll my gems using macgem in order to work with macirb using my existing .irbrc?
Yep. Gem installations are contained within the installation directory of the Ruby interpreter you're using. A possible solution to your problem could be something like this: unless defined?(RUBY_ENGINE) # require gems for the Ruby interpreter bundled with OSX. else # require gems for use with MacRuby. end Ruby 1.8 doesn't define RUBY_ENGINE as far as I know, but 1.9 and other Ruby implementations do(rbx, JRuby, …) The Ruby Version Manager(RVM) does a much better job at handling multiple Ruby installations(MacRuby included), so maybe you can have a look at that too: http://rvm.beginrescueend.com HTH, Rob.
