我正在尝试使用 安装digest-whirlpool，gem但出现错误：

Building native extensions.  This could take a while...
ERROR:  Error installing digest-whirlpool:
    ERROR: Failed to build gem native extension.

        /usr/bin/ruby1.9.1 extconf.rb
/usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require': cannot load such file -- mkmf (LoadError)
    from /usr/lib/ruby/1.9.1/rubygems/custom_require.rb:36:in `require'
    from extconf.rb:1:in `<main>'


Gem files will remain installed in /var/lib/gems/1.9.1/gems/digest-whirlpool-1.0.2 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/digest-whirlpool-1.0.2/ext/digest/whirlpool/gem_make.out

为什么会这样？

您可以尝试安装-devruby​​ 的版本。

尝试：

sudo aptitude install ruby1.9.1-dev

但如果我可以建议的话，RVM ( https://rvm.io ) 让处理不同版本的 ruby​​ 变得更加容易。
