the "ssl" parameter requires ngx_http_ssl_module

If you encounter the following error in Nginx:

nginx: [emerg] the "ssl" parameter requires ngx_http_ssl_module in /home/izeye/programs/nginx/conf/nginx.conf:99

add `--with-http_ssl_module` when running `./configure` as follows:
./configure --prefix=/home/izeye/programs/nginx --with-http_ssl_module
