Syntax Error.

Mac OS X (Mavericks) に Homebrew をインストール後、問題がないかチェックしてくれるbrew doctorというコマンドがあります。

これを実行したところ，Warningが出たので解決までの手順をメモ。

$ brew doctor
Warning: Unbrewed dylibs were found in /usr/local/lib.
If you didn't put them there on purpose they could cause problems when
building Homebrew formulae, and may need to be deleted.

Unexpected dylibs:
    /usr/local/lib/libmacfuse_i32.2.dylib
    /usr/local/lib/libmacfuse_i64.2.dylib
    /usr/local/lib/libosxfuse_i32.2.dylib

Warning: Your Homebrew is outdated.
You haven't updated for at least 24 hours, this is a long time in brewland!
To update Homebrew, run `brew update`.

なんかファイルを消せと言われてるので消す。

$ rm -rf /usr/local/lib/libmacfuse_i32.2.dylib
$ rm -rf /usr/local/lib/libmacfuse_i64.2.dylib
$ rm -rf /usr/local/lib/libosxfuse_i32.2.dylib
$ rm -rf /usr/local/lib/libosxfuse_i64.2.dylib
$ rm -rf /usr/local/lib/libosxfuse_i32.la
$ rm -rf /usr/local/lib/libosxfuse_i64.la
$ rm -rf /usr/local/lib/pkgconfig/osxfuse.pc

もう一度brew doctorを実行してみます。

次は削除したファイルのシンボリックリンクがエラーに。

$ brew doctor

brew pruneでシンボリックリンクをきれいにする。
