OSX El Capitan build issues #7175

I'm new to GitHub and this project, so I apologize if this isn't helpful. I have a new laptop with OS X and followed the instructions in doc/build-osx.md but can't get it to work.

There are some export issues, but I think they've already been reported in a pull request: http://fdecollibus.blogspot.com/2015/11/building-bitcoinlitecoin-on-mac-os-x.html

After following that, however, I have a new issue where build.h cannot be found (see below). I hesitated to report this because maybe I am just doing it wrong, but in that case maybe the instructions could be improved?

My-MacBook-Pro:bitcoin myuser$ make

Could you post your config.log somewhere and the output of brew info openssl as well as brew -v?

Sure, here you go: config.log.txt

Stephens-MacBook-Pro:bitcoin stephen$ brew -v
Homebrew 0.9.5 (git revision 911a; last commit 2015-12-05)


Stephens-MacBook-Pro:bitcoin stephen$ brew info openssl
openssl: stable 1.0.2e (bottled) [keg-only]
OpenSSL SSL/TLS cryptography library
https://openssl.org/
/usr/local/Cellar/openssl/1.0.2d_1 (464 files, 17M)
  Poured from bottle
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/openssl.rb
==> Dependencies
Build: makedepend ✘
==> Options
--universal
        Build a universal binary
--without-check
    Skip build-time tests (not recommended)
==> Caveats
A CA file has been bootstrapped using certificates from the system
keychain. To add additional certificates, place .pem files in
  /usr/local/etc/openssl/certs

and run
  /usr/local/opt/openssl/bin/c_rehash
This formula is keg-only, which means it was not symlinked into /usr/local.
Apple has deprecated use of OpenSSL in favor of its own TLS and crypto libraries

I can reproduce this. When I link OpenSSL via brew link openssl, configure finds the header and all is fine. When not, conftest does not find them. See config.txt. The corresponding line in the configure-script is:

ac_fn_cxx_check_header_mongrel "$LINENO" "openssl/ec.h" "ac_cv_header_openssl_ec_h" "$ac_includes_default"

Which may be generated by https://github.com/bitcoin/bitcoin/blob/master/configure.ac#L749 ? And maybe this ignores the $openssl_prefix?

Any progress here?
