尝试安装 pg gem 时遇到以下问题。我的操作系统是 Ubuntu 12.10。我已经安装了 postgresql（通过 postgres 页面上的安装程序）。我也完成了 apt-get install of libpq5and libpq-dev。这是错误：

ERROR:  Error installing pg:
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Provided configuration options:
    --with-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib

    --without-pqlib
