Python では simplejson がデファクトっぽい感じだったので、simplejson をインストールしようと思ったら、以下のようなエラーメッセージが。。。

 # wget http://pypi.python.org/packages/source/s/simplejson/simplejson-1.3.tar.gz#md5=fbe039b9b863572651a0f665acea34c9
 # tar zxvf simplejson-1.3.tar.gz 
 # cd simplejson-1.3
 # python setup.py install

---------------------------------------------------------------------------
This script requires setuptools version 0.6a11 to run (even to display
help).  I will attempt to download it for you (from
http://cheeseshop.python.org/packages/2.5/s/setuptools/), but
you may need to enable firewall access for this script first.
I will start the download in 15 seconds.

(Note: if this machine does not have network access, please obtain the file

   http://cheeseshop.python.org/packages/2.5/s/setuptools/setuptools-0.6a11-py2.5.egg

and place it in this directory before rerunning this script.)

そもそも setuptools というのが必要みたい。（ごめんなさい。私は Python はよくわからないです。。。）

で、setuptools のサイト http://pypi.python.org/pypi/setuptools にアクセスして、Mac OS X の項を見つつ、次のように実施しました。

  #  wget http://pypi.python.org/packages/2.5/s/setuptools/setuptools-0.6c9-py2.5.egg#md5=fe67c3e5a17b12c0e7c541b7ea43a8e6
  #  sh setuptools-0.6c9-py2.5.egg 

なんと setuptools のインストールはとても簡単。

そして引き続き、simplejson のインストール

 # python setup.py install
（中略）
Installed /Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/simplejson-1.3-py2.5.egg
Processing dependencies for simplejson==1.3
Finished processing dependencies for simplejson==1.3

すばらしい。あっさり入りましたぞ。

ってことで simplejson は setuptools があればあっさりインストールできますよ、というお話でした。

年末のテレビを見ながらダラダラと simplejson と setuptools を調べていた私でした。本年もどうぞよろしく。（なんのこっちゃ）
