問題1：

configure: error: Your OpenSSL headers do not match your
library. Check config.log for details.
If you are sure your installation is consistent, you can disable the check
by running “./configure –without-openssl-header-check”.
Also see contrib/findssl.sh for help identifying header/library mismatches.

解決辦法是指定你本地環境的openssl路徑：

./configure –with-ssl-dir=/usr/local/Cellar/openssl/1.0.2g

問題2：
cannot find input file: `config.h.in’

這個問題是這麼處理的：
vi configure.ac
set ff=unix
然後autoreconf
之後重新：
./configure –with-ssl-dir=/usr/local/Cellar/openssl/1.0.2g
即可configure成功！

最後configure成功之後是這樣的：
