Bug #9714: Ruby configured to call OpenSSL engine API when it shouldn't
https://bugs.ruby-lang.org/issues/9714

* Author: Barry Allard
* Status: Open
* Priority: Normal
* Assignee: 
* Category: ext/openssl
* Target version: current: 2.2.0
* ruby -v: ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]
* Backport: 2.0.0: UNKNOWN, 2.1: UNKNOWN
----------------------------------------
### (This issue is NOT related to the Heartbleed vulnerability.)

There is an issue compiling under OSX where system dependencies and homebrew dependencies get mixed together, resulting in an incorrectly configured Ruby which fails at runtime.


The attached patch to `ext/openssl/ossl.h` checks the actual configuration from `openssl/ssl.h`:

`#if defined(HAVE_OPENSSL_ENGINE_H) && defined(HAVE_ST_ENGINE) && !defined(OPENSSL_NO_ENGINE)`

instead of just

`#if defined(HAVE_OPENSSL_ENGINE_H) && defined(HAVE_ST_ENGINE)`  


## Patches

(Patches also available at https://gist.github.com/10092587)

### Testing

I've tested it on several ruby 1.9.x - 2.1.1 rebuilt from source, and it seems to Do The Right Thing (tm).

All Rubies fail in a similar manner, which was expected.


## Environment


### Ruby 2.1.1 configure options:

`--with-openssl-dir=/usr/local/opt/openssl --disable-install-doc --enable-shared`


### OpenSSL 1.0.1g Configure options:

`zlib-dynamic shared enable-cms no-hw no-rdrand no-sctp no-md4 no-mdc2 no-rc4 no-fips no-engine`
