strikes me that this isn't even cute and slick. what is the reason for hiding this? I have to assume someone using this would be aware of the requirement for these modules, or, at least, that there is a directory structure that this tar file they've unpacked has created. If they have been curious and competent enough to take on reading or modifing the source, why would we assume the need to hide these paths from them? Sure it's a nice trick, but a nice trick for no reason can't be a good idea...
