I get this from `ruby -v` (having installed 1.9.2): ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10.4.0] So, the revision number is very slightly different. Hard to say in this case whether that is worth uninstalling the one and installing the other. Probably not, but hard to say exactly.
