Símbolo no encontrado: _BIO_new_CMS

Soy nuevo en Mac y no entiendo por qué mi scrapy parece que ya no funciona. Sospecho que openssl no es válido en mi capitan.

Lo intenté:

pip install cryptography pip install pyOpenSSL brew install openssl 

y todavía me sale el error de abajo. ¿Hay alguna manera de que pueda solucionar esto?

Resuelvo este problema con el siguiente comando:

 LDFLAGS="-L/usr/local/opt/openssl/lib" pip install cryptography --no-use-wheel
