When python is being run from a compile environment, it detects this by looking for "Lib" folders in directories above the one containing the executable. (I always thought that this "special" execution mode, hardwired in, was a bit odd, and suggested that this could be made a function of pep405) Anyway, keeping your executable as part of the tree is the trick I use, and to make things nice I put right next to it: site.py sitecustomize.py
sitecustomize.py is where you would put the logic to set sys.path by walking up the hierarchy and finding the proper root. site.py is there to merely import sitecustomize.py, in case a site.py is not found in all the default places python looks.
