MacBookAirへHomeBrewを導入。

長らくMac Portsだったけれど、周りの人達が皆HomeBrewを押してくるのでそっちに切り替えてみるテスト。

$ /usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)"

==> This script will install:

/usr/local/bin/brew

/usr/local/Library/Formula/...

/usr/local/Library/Homebrew/...

Press enter to continue

==> Downloading and Installing Homebrew...

==> Installation successful!

You should run `brew doctor' *before* you install anything.

Now type: brew help

matsumura$ brew doctor

Warning: You have no /usr/bin/cc.

This means you probably can't build *anything*. You need to install the Command

Line Tools for Xcode. You can either download this from http://connect.apple.com

or install them from inside Xcode's Download preferences. Homebrew does not

require all of Xcode! You only need the Command Line Tools package!

Warning: Git could not be found in your PATH.

Homebrew uses Git for several internal functions, and some formulae use Git

checkouts instead of stable tarballs. You may want to install Git:

  brew install git

Warning: You have Xcode 3.2.4, which is outdated.

Please install Xcode 4.3.

Warning: You have Macports or Fink installed.

This can cause trouble. You don't have to uninstall them, but you may like to

try temporarily moving them away, eg.

  sudo mv /opt/local ~/macports

Warning: Your Homebrew is outdated

You haven't updated for at least 24 hours, this is a long time in brewland!

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/libusb-1.0.0.dylib

Warning: Unbrewed .la files 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 .la files:

    /usr/local/lib/libusb-1.0.la

Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.

If you didn't put them there on purpose they could cause problems when

building Homebrew formulae, and may need to be deleted.

Unexpected .pc files:

    /usr/local/lib/pkgconfig/libusb-1.0.pc

Warning: Unbrewed static libraries 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 static libraries:

    /usr/local/lib/libusb-1.0.a

Warning: Your Xcode is configured with an invalid path.

You should change it to the correct path. Please note that there is no correct

path at this time if you have *only* installed the Command Line Tools for Xcode.

If your Xcode is pre-4.3 or you installed the whole of Xcode 4.3 then one of

these is (probably) what you want:

    sudo xcode-select -switch /Developer

    sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer

DO NOT SET / OR EVERYTHING BREAKS!
