Description of problem:

After I install python-dap (http://pydap.org/), using a rpm I locally
build, with the usual:

%build
%{__python} setup.py build


%install
rm -rf %{buildroot}
%{__python} setup.py  install --single-version-externally-managed -O1
--skip-build --root %{buildroot}

setuptools traceback, for example when rebuilding setuptools itself:

+ /usr/bin/python setup.py build
Traceback (most recent call last):

paster also traceback with a similar message.

I found that on the web:
http://mail.python.org/pipermail/distutils-sig/2006-March/006177.html

Version-Release number of selected component (if applicable):

setuptools-0.6c3-1.1

I get the same when rebuilding with 
setuptools-0.6c5

As a side note, it could be relevant to update python-setuptools to
that version.
