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?

Yes, and it shouldn't be, since its __init__.py contains actual code, and is missing a namespace declaration. (The whole point of a namespace package is that the package itself shouldn't contain any code. After all, in a --single-version-externally-managed install, the __init__.py will not even be *there*.) So, this is a packaging error on the part of the quadtree developer(s). Most likely, quadtree is not really a namespace package and should not be declared as one, because the only reason to do that is if there are modules or subpackages under that package that are distributed *separately*. My guess is that the author saw a namespace declaration in some other project's setup.py and thought it was required boilerplate instead of an option.

20070118/externals/Quadtree/quadtree/__init__.py", line 2, in <module> from _tree import Quadtree ImportError: No module named _tree

cat quadtree/__init__.py

from _tree import Quadtree

And, here is the setup.py file:
