homebrewを使ってみた

インストールはhttp://wiki.github.com/mxcl/homebrew/installation に記載されている ruby のコマンドを実行するだけ。簡単。

さっそく python のインストールをしてみる。

$ sudo brew install python
Warning: It appears you have Macports or Fink installed
Although, unlikely, this can break builds or cause obscure runtime issues.
If you experience problems try uninstalling these tools.

==> Caveats
readline is keg-only. This means it is not symlinked into Homebrew's
prefix. The formula provides the following rationale:

OS X provides the BSD Readline library. In order to prevent conflicts when
programs look for libreadline we are defaulting this GNU Readline installation
to keg-only.

Generally there are no consequences of this for you, however if you build your
own software and it requires this formula, you may want to run this command to
link it into the Homebrew prefix:

    brew link readline

==> Caveats
The site-packages folder for this Python is:
  /usr/local/Cellar/python/2.6.5/lib/python2.6/site-packages

We've added a "homebrew.pth" file to also include:
  /usr/local/lib/python2.6/site-packages

You may want to create a "virtual environment" using this Python as a base
so you can manage multiple independent site-packages. See:
  http://pypi.python.org/pypi/virtualenv

If you install Python packages via pip, binaries will be installed under
Python's cellar but not automatically linked into the Homebrew prefix.
You may want to add Python's bin folder to your PATH as well:
  /usr/local/Cellar/python/2.6.5/bin
==> Summary
/usr/local/Cellar/python/2.6.5: 4452 files, 74M, built in 2.8 minutes

どうやら、パッケージとバージョンできっちりディレクトリ分けてインストールされる模様。

パスの設定をして完了っと。
