td-agentをhomebrewでインストールする

だいたいここの手順でいけるが、ちょっとだけ手詰まりがあったのでメモ。

環境 : Mavericks

• ruby-build の HEAD が入ってた

==> RUBY_CONFIGURE_OPTS="--with-openssl-dir=/usr/local/Cellar/openssl/1.0.1f --with-readline-dir=/usr/local/Cellar/readline/6.2.4" /usr/local/Cellar/ruby-build/20140225/bin/ruby-
sh: /usr/local/Cellar/ruby-build/20140225/bin/ruby-build: No such file or directory

symlink張って解決。

% ln -s /usr/local/Cellar/ruby-build/HEAD /usr/local/Cellar/ruby-build/20140524

• brew link が失敗する

Error: The `brew link` step did not complete successfully
The formula built, but is not symlinked into /usr/local
You can try again using:
  brew link td-agent

libyaml がconflictしていた。brew の親切アドバイスどおりで解決。

% brew link td-agent
Linking /usr/local/Cellar/td-agent/1.1.17... 
Error: Could not symlink include/yaml.h
Target /usr/local/include/yaml.h
is a symlink belonging to libyaml. You can unlink it:
  brew unlink libyaml

To force the link and overwrite all conflicting files:
  brew link --overwrite td-agent

To list all files that would be deleted:
  brew link --overwrite --dry-run td-agent
% brew unlink libyaml
Unlinking /usr/local/Cellar/libyaml/0.1.6... 5 symlinks removed
% brew link --overwrite td-agent
Linking /usr/local/Cellar/td-agent/1.1.17... 38 symlinks created
