philomory is doing similar things here:
http://www.libgosu.org/cgi-bin/mwf/topic_show.pl?tid=43My problem is that I've always used, as a developer and user, the One Click Ruby Installer, and that is still 1.8. Given that Ruby 1.9 contains RubyGems, there is probably no real need for a One-Click Installation anymore? Do you know if there is a One True 1.9 Installer that I can use to play around with it?
I'm even considering switching to 1.9 *only* if a dual system turns out not to work. 1.9 is just much better suited for gamedev.
