The URL in the package is obsolete, but kindly redirected to the new one: http://xael.org/norman/python/pyclamd/ (in ebuild) -> http://xael.org/pages/pyclamd-en.html Pypi has a more recent version (0.4.0), which seems to be the same package (same author/homepage) : https://pypi.python.org/pypi/pyClamd I think the author just forgot to update its own page, pypi is where stuff happens nowadays.
