cpanでupdateすると以下のメッセージが出て、DB_Fileモジュールのアップデートに失敗する。"No library found for -ldb"と言われるし、"error: db.h: No such file or directory"といわれてインストールに失敗する。

まずは以下のように導入済みのパッケージからdb.hを検索してみる。存在しないことがわかる。つまり、ライブラリパスの設定が間違っているわけではないと思われる。
# dpkg --search db.h linux-libc-dev: /usr/include/linux/adb.h libc6-dev: /usr/include/netdb.h libssl-dev: /usr/include/openssl/txt_db.h libc6-dev: /usr/include/rpc/netdb.h libc6-dev: /usr/include/bits/netdb.h libc6-dev: /usr/include/thread_db.h
未導入のパッケージにdb.hが含まれる場合には、webの検索インターフェイスをつかう。複数のパッケージがdb.hというファイルを提供することがわかる。さらに絞り込みを行うために、libdb.aが含まれるパッケージを検索する。これにより、導入するべきパッケージはlibdb4.6-dev, libdb4.7-dev, libdb4.8-devの3つに絞られる。バージョン違いのパッケージのように思われるので、透過的に適当なパッケージを選択してインストールするダミーのパッケージが無いか検索すると以下のようになる。それっぽいパッケージの名前はlibdb-devだと判る。webから内容を確認すると、これをインストールすることで適当なバージョンが選択されることがわかる。
