Setting Some Environment Variables
Setup, Iteration 3

To use a more up-to-date version of rubygems, I've installed it in the CS 214 slop directory. To use it, you'll need to set some environment variables:

export GEM_PATH=/home/cs/214/local/gems
export GEM_HOME=/home/cs/214/local/gems
export RUBYLIB=/home/cs/214/local/lib
