【问题描述】：
我正在使用 ruby 运行 Ubuntu：
ruby 1.9.3p484 (2013-11-22 revision 43786) [x86_64-linux]
安装了 Sass 3.4.9，现在我尝试从 http://compass-style.org/install/ 安装 Compass，但运行 gem install compass 时出现错误：
Building native extensions. This could take a while...
ERROR: Error installing compass:
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 extconf.rb:4:in `<main>'
Gem files will remain installed in /var/lib/gems/1.9.1/gems/ffi-1.9.6 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/ffi-1.9.6/ext/ffi_c/gem_make.out
这是日志文件内容：
/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:4:in `<main>'
我已经在谷歌上搜索了几个小时，但仍然卡住了。如何解决？
