I just would like to know if I would ALWAYS find the install directory in sys.path[6] and site-packages directory in sys.path[7] on any Win32 platform and sys.path[2] and site-packages directory in sys.path[6] on any Linux platform. If the reply is : "YES you can be sure of it !" All would be great for me and I would be ready to create a script to detect with a reliable manner the installation dir. et site-packages dir. for all my Linux/Win32 Python apps.
