An error occurred when trying to install cryptography 0.9.3. Look above this message for any errors that were output by easy_install.
While:
  Installing django.
  Getting distribution for 'cryptography>=0.7'.
Error: Couldn't install: cryptography 0.9.3
我跑过：

brew install openssl
brew install pkg-config libffi
env ARCHFLAGS="-arch x86_64" LDFLAGS="-L/usr/local/opt/openssl/lib" CFLAGS="-I/usr/local/opt/openssl/include"
pip install cffi
我注意到我的机器已经有一个旧版本的openssl，所以我创建了一个新版本的符号链接：

openssl version
OpenSSL 1.0.1f 6 Jan 2014
mv /sw/bin/openssl /sw/bin/openssl_OLD
ln -s /usr/local/Cellar/openssl/1.0.2d_1/bin/openssl /sw/bin/openssl
openssl version
OpenSSL 1.0.2d 9 Jul 2015
我还可以确认我有一台64位机器：

file /sw/lib/libffi.6.dylib
/sw/lib/libffi.6.dylib: Mach-O 64-bit dynamically linked shared library
运行依赖项为cryptography==0.7的同一脚本会导致相同的错误

我正在运行GCC4.2

到目前为止，我所做的任何尝试都无法改变我在django buildout中遇到的错误：（当我运行pip install cryptography时，它似乎安装得很干净，但此buildout脚本坚持安装本地副本

有人对我下一步应该尝试什么有什么建议吗？我已经没有主意了。

所以问题出在
brew安装openssl
1.0.2d版上

我切换到使用
端口安装openssl
和中所述的相同env标志 这意味着构建成功完成

但是，当尝试运行
/bin/django migrate
时，我遇到了另一个错误：

  raise ImproperlyConfigured("Error loading psycopg2 module: %s" % e)
django.core.exceptions.ImproperlyConfigured: Error loading psycopg2 module: dlopen(/Users/<user>/Sites/<site>/eggs/psycopg2-2.6-py2.7-macosx-10.8-x86_64.egg/psycopg2/_psycopg.so, 2): Library not loaded: /usr/local/opt/openssl/lib/libssl.1.0.0.dylib
