i downloaded a Blender build from graphicall that had a .sh file used to set environment variables targeting that directory and its subdirectories. anyway, long story short, i ended up not liking the build, so i unset the other variables, and now i’m needing to reset the PYTHONPATH variable.
i have python 2.7 and 3.2 installed, but i’m still something of a n00b with Ubuntu and im not sure how to reset the PYTHONPATH variable to its original value. what is it “supposed” to be in Ubuntu 11.04?
edit: i know HOW to set an environment variable 
i just don’t know what to set it BACK to. just clarifying.
