As of 0.14, pyOpenSSL is a pure-Python project. That means that if you encounter any kind of compiler errors, pyOpenSSL’s bugtracker is the wrong place to report them because we cannot help you.

Please take the time to read the errors and report them/ask help from the appropriate project. The most likely culprit being cryptography that contains OpenSSL’s library bindings.
