MacOSXのDeveloper Toolsでデフォルトでインストールされていなかったので，インストール．

libwww-perl

libwww-perlというライブラリにだいたい，Web関係のヤツはそろっているようだ．
libwww-perl
ここからダウンロードして，インストール．
とりあえず，オプションは，言われたとおりにデフォルトでやってみた．

>perl Makefile.PL
This package comes with some sample programs that I can try
to install in /usr/bin.
Note that you can avoid these questions by passing
the '-n' option to 'Makefile.PL'.
Do you want to install lwp-request? [y] y
Do you want to install lwp-mirror? [y] y
Do you want to install lwp-rget? [y] y
Do you want to install lwp-download? [y] y
The lwp-request program will use the name it is invoked with to
determine what HTTP method to use.  I can set up alias for the most
common HTTP methods.  These alias are also installed in
/usr/bin.
Do you want to install the GET alias? [n] n
Do you want to install the HEAD alias? [n] n
Do you want to install the POST alias? [n] n
