【问题描述】：

试图捆绑一个有gem geoip-c但得到的应用

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

/Users/durrantm/.rvm/rubies/ruby-2.1.5/bin/ruby -r ./siteconf20151116-4194-j
cyop7.rb extconf.rb
checking for iconv_open() in iconv.h... no
checking for iconv_open() in -liconv... yes
checking for GeoIP_record_by_ipnum() in -lGeoIP... no
you must have geoip c library installed!
*** extconf.rb failed ***
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
        --without-opt-dir
        --with-opt-include

如何克服这个问题？

我可以brew install geoip 和现在brew list geoip 显示

/usr/local/Cellar/geoip/1.6.7/bin/geoiplookup
/usr/local/Cellar/geoip/1.6.7/bin/geoiplookup6
