Same here. In aggregate, I must have spent at least a two full days getting therubyracer and libv8 working in various environments.

As a recent Java refugee, one of the things I find most painful about Rails is its dependence on native code libs. It's really a lot of work to get the dependencies sorted out, especially if you have several platforms to support (say OSX for dev, and multiple Linux flavors for staging/prod).

One thing I learned (the hard way) is to heed the advice that "rvm requirements" offers. If you install the libs that it recommends before trying to install your gems, things will go more smoothly. This may sound obvious, but when you're installing Ruby, RVM, Rails, Apache, etc, it's easy to overlook the instructions.
