操作系统：Ubuntu 10.04 LTS
乘客：passenger-3.0.13
Nginx：nginx-1.2.1
尝试使用许多配置从源 nginx + 乘客安装，除了“默认”之外没有任何工作。
这有效：
--prefix=/opt/host/nginx --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt=-Wno-error --add-module=/usr/local/src/passenger-3.0.13/ext/nginx
这失败了：
--prefix=/opt/host/nginx --with-http_ssl_module --with-http_gzip_static_module --with-cc-opt=-Wno-error --add-module=/usr/local/src/passenger-3.0.13/ext/nginx --conf-path=/etc/nginx/nginx.conf --error-log-path=/var/log/nginx/error.log --pid-path=/var/run/nginx.pid --lock-path=/var/lock/nginx.lock --http-log-path=/var/log/nginx/access.log
