我知道它缺少依赖项，但我认为 CPAN 会自动安装所有依赖模块。这是错误：

然后我尝试单独安装一个依赖模块：
cpan[2]> install PadWalker
Running install for module 'PadWalker'
Running make for R/RO/ROBIN/PadWalker-1.96.tar.gz
Has already been unwrapped into directory /root/.cpan/build/PadWalker-1.96-n6C9km
Could not make: Unknown error
Running make test
Can't test without successful make
Running make install
Make had returned bad status, install seems impossible
有人能指出我正确的方向吗？我是 root，到目前为止它是最新的 Ubuntu 12.04.1。
