Hello,
I would like to update Ruby in instant rails from 1.8.6 to 1.9.2, but it is not just simple to extract and replace into ruby folder because i loose all gems like actionmailer etc... also i can't replace only ruby.exe because i get errors when i want to use gem update, see i updated gem to 1.3.7 version from 1.0.1 and the only thing is to update ruby version because at least i need to use 1.8.7 to update rails etc..
