If you’re getting a failure from ‘rvm install rbx’ during the ‘Configuring rbx’ stage, and your logfile looks like:
[2011-05-20 23:22:41] /Users/austinmills/.rvm/wrappers/ruby-1.8.7-p302/rake install /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:827:in `report_activate_error': Could not find RubyGem rake (>= 0) (Gem::LoadError) from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:261:in `activate' from /System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/1.8/rubygems.rb:68:in `gem' from /usr/bin/rake:18
Then you just need to make sure that rake is installed in your global gemset (‘rvm use 1.8.7@global’ and ‘gem install rake’).
