Попытка установить Scrapy - ошибка: Не удалось найти «openssl.exe»

Есть мысли, как решить эту проблему? Я использую pip для установки Scrapy на машину с Win XP Pro SP 3. У меня на машине установлен Python 2.7. Кажется, проблема с pyOpenSSL. Я получаю сообщение об ошибке «Не удалось найти файл openssl.exe».

Вот мой лог-файл. Мне пришлось немного его взломать из-за URL-адресов в нем.
