[Distutils] failing to build quadtree if the package is already installed

26 Jan 2007

      Hi All,

Sorry if this kind of thing has already been discussed.  I am packaging
quadtree for Mac OSX/fink (deb based package management) and am getting a
failed build if the package is alread installed and I am trying to do a
rebuild.  Can someone point me at what needs to be changed?  Is this because
quadtree is a namespace?

Thanks!
