  <p>I tried downloading latest version from here: <a href="https://pypi.python.org/pypi/python-ldap#downloads" rel="nofollow">https://pypi.python.org/pypi/python-ldap#downloads</a>, but it seems thats the same version as it gives same error. Am I missing something here or this version is bugged?</p>
  
  <p><strong>Update</strong>
  I think I should have included this message of error too. This goes before that one:</p>
  
  <p><code>error: command 'gcc' failed with exit status 1</code></p>
