Thank you for the advice, Valery. I tried that, and (I believe) followed the instructions at the rvm page. I say I *believe*, because these instructions always seem to lead to a number of things that one might reasonably try, though there's no clear notion of what one really should be doing.... argh. anyway, I got to the last instruction, which is to type rvm install 1.9.3, and I got the following:
joelrwesley$ rvm install 1.9.3 Fetching yaml-0.1.4.tar.gz to /Users/joelrwesley/.rvm/archives Extracting yaml-0.1.4.tar.gz to /Users/joelrwesley/.rvm/src Configuring yaml in /Users/joelrwesley/.rvm/src/yaml-0.1.4.

Halting the installation. joelrwesley$ So I went in and read the log.
