I have tried to install the latest setuptools for Python 2.5<br>by using the script&nbsp; ez_setup.py from PEAK&#39;s website<br>but the script aborts with the error:<br><br>File &quot;/opt/local/lib/python2.5/hashlib.py&quot;, line 31, in __get_builtin_constructor
<br>&nbsp;&nbsp;&nbsp; import _md5<br>ImportError: No module named _md5<br><br>With the official Python 2.5 distribution such an error<br>doesn&#39;t occur and the command &quot;from hashlib import md5&quot;<br>works flawlessly.<br>
