title: How to change path to site-packages dir in easy_install
body: <p>I'm trying to use easy_install on windows7x64 and getting this:</p>
  <pre><code>&lt;output&gt;
  c:\Python27\Scripts&gt;easy_install.exe django-piston
  error: can't create or remove files in install directory
  
  The following error occurred while trying to add or remove files in the
  installation directory:
  
      [Errno 2] No such file or directory: 'C:\\Python27\\Lib\\site-packages\\Lib\
  \site-packages\\test-easy-install-4132.pth'
  
  The installation directory you specified (via --install-dir, --prefix, or
  the distutils default setting) was:
  
      C:\Python27\Lib\site-packages\Lib\site-packages\
  
  This directory does not currently exist.  Please create it and try again, or
  choose a different installation directory (using the -d or --install-dir
  option).
  </code></pre>
  
  <p>Where can I change easy_install's path to correct one &quot;C:\Python27\Lib\site-packages&quot;?</p>
