doesn't work: distutils ends up trying to overwrite (readonly)
original source files.

consider PIL, for example: in my source directory, I have the
following files, checked out from a repository:


I want to be able to run setup.py and end up with an _imaging.pyd
in the same directory.  I don't want distutils to attempt to copy
stuff from PIL/*.py to PIL/*.py, mess up other parts of my source
tree, install any scripts (broken or not) in the Python directory, or
just generally make an ass of itself when failing to copy readonly
files on top of other readonly files.

the following is a bit more reliable (windows version):

    rd /s /q build
    python setup.py build
    rd /s /q install
    python setup.py install --prefix install
    copy install\*.pyd .

if distutils didn't mess up when deleting readonly files it created all
by itself, the following command could perhaps work:

    setup.py install_ext --install-lib=3D.

but there is no install_ext command in the version I have...
