乘客安装Apache错误

我在debian wheezy raspberry pi上运行红宝石和红宝石宝石 . 当我在安装apache2和passenger gem之后运行 passenger-install-apache2-module 命令时，它会在检查所有组件都已安装时给出：

Apache:
Use of uninitialized value $includedir in concatenation (.) or string at (eval 9) line 1.
Use of uninitialized value $includedir in concatenation (.) or string at (eval 9) line 1.

然后当它开始编译时，它会显示：

Compiling and installing Apache 2 module...

我尝试重新安装apache和乘客，但错误仍然存在 . Apache通常以其他方式运行

编辑：未安装apache标头时不会发生'未初始化的值'警告 . 一旦我安装它们，就会发生错误 .
