[Distutils] setuptools-0.6c11 package_index.py 475 return dist.clone ?

Folks, in setuptools-0.6c11-py2.6.egg/setuptools/package_index.py lines 468-475 if dist is None: ... return dist.clone(...) => of course AttributeError: 'NoneType' object has no attribute 'clone' return None if dist is None else dist.clone(...) fixes yolk. (Does nobody else use yolk ? I like it, less is more; which of this year's new package managers have the same functionality ?) Sorry if this is a duplicate or the wrong place to post. cheers -- denis
