【问题描述】：
我在尝试安装 geoip_city gem 时不断收到错误消息。我已经将 GeoIP C 库安装到 /opt/GeoIP，但 gem 似乎没有选择它。我试过了：
sudo gem install geoip_city -- --with-geoip-dir=/opt/GeoIP
sudo gem install geoip_city -- --with-geoip-lib=/opt/GeoIP/lib
sudo gem install geoip_city -- --with-geoip-dir=/opt/GeoIP --with-geoip-lib=/opt/GeoIP/lib
所有这些都输出这个错误：
Building native extensions. This could take a while...
ERROR: Error installing geoip_city:
ERROR: Failed to build gem native extension.

you must have geoip c library installed!

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:

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/geoip_city-0.2.0 for inspection.
