    spurvis:~ rogue$ ruby -v
    ruby 1.8.7 (2010-01-10 p         


        

Answer 1

If you're running a fresh copy of Lion & Xcode 4.2, you're going to need to install the GCC 4.2 dev libraries first - they aren't included in a fresh Xcode 4.2 install.

Then pass the CC="/usr/bin/gcc-4.2" flag when installing your rvm.

Be sure to rvm remove any previous installation attempts first.
