在Ubuntu 14.04上安装Ruby Capybara webkit 1.4.1失败

我正试图按照他们的wiki安装最新版本的capybara webkit（1.4.1），并安装了qt5：

sudo apt-get install qt5-default libqt5webkit5-dev

但是

gem install capybara webkit

总是会从g++中得到以下编译错误：

    ERROR:  Error installing capybara-webkit:
        ERROR: Failed to build gem native extension.
