	It's not about which ruby you're installing on the system, really 
anything other than 1.8.7 as system Ruby is a pain in the ass at this 
point.

kashani@gentoo64 ~ $ rvm list
rvm rubies

    rbx-head [ ]
    ree-1.8.7-2011.03 [ x86_64 ]
    ruby-1.9.2-p180 [ x86_64 ]
=> ruby-1.8.7-p334 [ x86_64 ]

	Using RVM I can have all version and implementations of Ruby and 
multiple gem sets per Ruby as well. That way I can work on 
ruby-1.8.7@rail2 app or switch to ruby-1.92@rails3 which keep the gems 
separate. Also I avoid breaking the system when doing wacky things in my 
dev environment.
