Build fails on Mac OS X 10.11

During the build process, this eventually happens...

running: "cc" "-O3" "-ffunction-sections" "-fdata-sections" "-m64" "-fPIC" "-o" "/Users/njenning/code/projects/mysteryshack/target/release/build/openssl-sys-f0bee5fb97afc90d/out/src/openssl_shim.o" "-c" "src/openssl_shim.c"
ExitStatus(Code(1))


command did not execute successfully, got: exit code: 1



--- stderr
src/openssl_shim.c:1:10: fatal error: 'openssl/hmac.h' file not found

Same issue as sfackler/rust-openssl#255. Unfortunately I don't think we'll ever be able to get rid of the openssl dependency.

So, in case you want to make note of it, the following worked:

$ brew install openssl
$ brew link --force openssl
