Updating Ruby gems on Leopard? Proceed with caution!
Remember this crucial step before running sudo gem update.
If you're updating to Leopard or working off a new Mac machine, before running sudo gem update make sure you have installed XCode Tools (located on your installation disk). Or else you'll probably get this sucky error:
ERROR: Error installing fastthread:
ERROR: Failed to build gem native extension.
/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby extconf.rb update can't find header files for ruby.
