The FXRuby binary gem for OS X is built on my MacBook, which is  
running Leopard (10.5.x). So it's based on the Ruby that comes  
preinstalled with Leopard, and the X server that ships with that OS  
version, etc. So yes, you're going to need to either build it from  
source (with help from Fink for some of the dependencies).

Hope this helps,
