Somehow I have ended up with v2.0.2 on my Mac. I am running Leopard so am not sure whether this version came with it. Here are the various versions of components:
macfizz$ rails -v
macfizz$ ruby -v
ruby 1.8.6 (2007-09-24 patchlevel 111) [universal-darwin9.0]
macfizz$ gem -v
Anyway, for various reasons I'm not that happy with 2.0.2 and want to downgrade my entire installation to where it was working nicely. I don't know either the version numbers I need (though I think I am looking for v 1.8.x of Rails and whatever goes with that)
Can anyone point me to suitable documentation for doing this?
