The problem is caused by pysqlite. If you look at it's PyPi page as
seen by buildout / setuptools [1] you'll notice a number of links, all
of which will be checked and accessed by buildout / setuptools.

Among those are for example:

http://pysqlite.org/
http://initd.org/pub/software/pysqlite/releases/2.3/2.3.3/
http://oss.itsystementwicklung.de/download/pysqlite/2.4/2.4.1/

The first one of these produces the NameError, as the domain isn't
registered anymore. The later two resolve, but point to pages stating
"This domain is for sale".

The easiest way would be for the maintainer of pysqlite to remove
these entries, by editing the old release metadata on PyPi. In your
own buildout you can probably only work around this by using your own
index and disallowing access to PyPi. I tried once to put in a
find-links to the actual version I wanted and a version pin, but this
still doesn't stop buildout to check all those links. Maybe you could
also get this to work with a dedicated zc.recipe.egg part for pysqlite
and an index restriction for just that part.
