title: twisted on centos missing mail.smtp?
body: <p>I'm trying to get buildbot running on centos5, and getting the following error:</p>
  
  <pre><code>  File "/usr/lib/python2.4/site-packages/buildbot/status/mail.py", line 14, in ?
      from twisted.mail.smtp import sendmail, ESMTPSenderFactory
  ImportError: No module named mail.smtp
  </code></pre>
  
  <p>I have the following twisted packages installed (and don't see anything else relevant to install):</p>
  
  <pre><code>$ rpm -qa | grep twisted
  python-twisted-web-0.7.0-1.el5
  python-twisted-core-2.5.0-4.el5
  python-twisted-words-0.5.0-3.el5
  </code></pre>
  
  <p>I'm more familiar with debian where I can do:</p>
  
  <pre><code>$ apt-file find twisted/mail/smtp
  python-twisted-mail: /usr/share/pyshared/twisted/mail/smtp.py
  </code></pre>
  
  <p>Two questions:</p>
  
  <ol>
  <li>Is there something I can pull from yum that will provide this file or do I need to resort to manual tactics for this part of twisted?</li>
  <li>Is there anything analogous to the <code>apt-file</code> command above for rpm/yum-based systems?</li>
  </ol>
  
  <p>Thanks.</p>
  
  <p>(I considered superuser, but this seems so tightly coupled to programming that I expect better answers here...)</p>
