How do I set a custom path in textmate to find my ruby files?

Question

I'm new to programming and trying to learn Ruby through some online tutorials. I have textmate and have created a Ruby folder in my Documents folder to hold my .rb files. While working through "Why's Poignant Guide" I came a across a two file program. One file attempts to 'require' the other. However, this doesn't work in this folder. Is there anyway to set textmate up to look here. I've come across a few sites that seem to be addressing this but I don't understand how file paths work in Unix.

You'll have to set the RUBYLIB variable to the directory that contains your files. Let's say it's at ~/Documents/Ruby (that is, a folder "Ruby" in your "Documents" folder). ~ is shorthand for /User/yourusername, so the full path to the directory is /Users/yourusername/Documents/Ruby. You'll set this as RUBYLIB in TextMate, which you can do by going to Preferences -> Advanced -> Shell Variables, then click the "+" button and add RUBYLIB as the "Variable" and /Users/yourusername/Documents/Ruby as the "Value".
