cabal: Missing dependency on a foreign library:
* Missing C library: pcre
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
Failed to install pcre-light-0.4
cabal: Error: some packages failed to install:
mysql-simple-0.2.2.4 depends on pcre-light-0.4 which failed to install.
pcre-light-0.4 failed during the configure step. The exception was:
ExitFailure 1
persistent-mysql-1.2.1 depends on pcre-light-0.4 which failed to install.
pcre-light が必要らしいので cabal からインストールを実行する。
# cabal install pcre-light-0.4

足りない依存ライブラリでエラーが起きているので、下記のコマンドでライブラリをインストールする。
