therubyracer Segmentation fault in rails 3.1.0.RC4

I have no idea where to start debugging being a newbie. I got the code from someone else and is trying to set it up. I run the server and see a part of the page and the server stopped. Please help! Thanks in advance. Here is the trace:

You are using older versions of execjs and therubyracer. Versions of execjs and therubyracer prior to 1.1.3 and 0.9.2 respectively did not properly lock V8. These crashes have since been fixed. I would recommend upgrading both of these gems to their latest versions.

Did you install a javascript runtime framework? TheRubyRacer needs that to work? For my ubuntu VPS I had to do that manually. Mac OS X ships with this.
