title: Cannot import ephem
body: <p>I'm having a problem importing ephem under windows.  I think it is a 32/64 bit problem.</p>
  
  <pre><code>Z:\&gt;python
  Python 2.7.2 (default, Jun 12 2011, 14:24:46) [MSC v.1500 64 bit (AMD64)] on win32
  Type "help", "copyright", "credits" or "license" for more information.
  &gt;&gt;&gt; import ephem
  Traceback (most recent call last):
    File "&lt;stdin&gt;", line 1, in &lt;module&gt;
    File "C:\Python27\lib\site-packages\ephem\__init__.py", line 5, in &lt;module&gt;
      import ephem._libastro as _libastro
  ImportError: DLL load failed: %1 is not a valid Win32 application.
  &gt;&gt;&gt;
  </code></pre>
  
  <p>I would rather not have 32 and 64 bit python on the same machine if I can avoid it.</p>
  
  <p>Thanks,<BR>
