[Distutils] easy_install question

- When I run 'easy_install ctypes', the behaviour depends on the current directory. If I run this when the current dir contains a 'ctypes' subdirectory, it doesn't search pypi^H^H^H^HCheeseShop for this name, instead it seems to attempt to install from source in that directory. Is that intended? Can I override this behaviour? - When I install a package which requires another package is there a way to specify a download url for the required package? Thomas
