If you want to deploy perfect forward secrecy and you use a RedHat, Centos or Fedora based system you likely won’t be able to do so without building your own OpenSSL. This is because by default the OpenSSL packages for these systems do not include ECC or ECDH and when web-servers like apache and Nginx are built against libraries that do not support them they obviously omit support for the algorithms.
Hopefully these distributions and the community repositories that support them will start including support for these algorithms by default soon but in the meantime you can add support by building your own.
