私はLinuxに慣れてきており、現在Backtrack 5に切り替えて、セキュリティの学校での練習を始めています。たくさんのgemファイルをインストールするmsfupdateを実行しています。 gemからPGをインストールしているときに、このエラーが発生します。どうすれば修正できますか?

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers. Check the mkmf.log file for more

An error occured while installing pg (0.15.0), and Bundler cannot continue.
Make sure that `gem install pg -v '0.15.0'` succeeds before bundling.
エラーが指摘しているように、問題はconfigureがlibpq-fe.h
を見つけられないことです。 BacktrackはDebianに基づいているので、libpq-dev
パッケージをインストールするヘッダーを取得できます。だから前にそれをインストールする
$ Sudo apt-get install libpq-dev
そしてさらに試みる。
