Automatically executed scripts don't pick up stuff from a specific users 
environment, its best to assume they're blank slates.   General rule of 
thumb is to always set the entire environment you want at the start of 
any script, otherwise what works when manually executed won't work 
automatically, or might not work how you intend.
