Ubuntuでgemのfcgiをインストールする際に必要となるパッケージ

自宅や会社のPCにfcgiのgemをインストールする際に、いつも以下のエラーが出力されてて、それをググっているので、自分用のメモとして記録しておく。

$ sudo gem install fcgi
　
Building native extensions. This could take a while...
ERROR: Error installing fcgi:
ERROR: Failed to build gem native extension.

/usr/bin/ruby1.8 extconf.rb install fcgi

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
--without-opt-include=${opt-dir}/include
--with-opt-lib

Gem files will remain installed in /var/lib/gems/1.8/gems/fcgi-0.8.7 for inspection.

interu@ubuntu:~/project/skip$ sudo gem install libfcgi-dev
ERROR: could not find gem libfcgi-dev locally or in a repository

このエラーが出力された場合は、fcgiのパッケージ以外に、以下のfcgiのパッケージをインストールすることで解決するはず。

$ sudo apt-get install libfcgi-dev
