Setting up HomeBrew on Mac Mini

Building blocks: Homebrew, XCode, X11, and Git

This guide is for starting from a fresh Mountain Lion install, with nothing else installed. You can approximate that state, by getting rid of all your macports and finks and what have you. Delete your /usr/local. Uninstall all XCodes are their developer tools.

Install homebrew:

ruby <(curl -fsSk https://raw.github.com/mxcl/homebrew/go)

Homebrew lets us effortlessly install things from source. It is good, but it needs some help: Mountain Lion doesn’t come with developer tools, and homebrew is not able to do much right now.

Go to the App Store and download XCode (I am writing this in early August 2012, and the current version is 4.4). This can take a little bit, so while it’s downloading, let’s install X11 libraries that Mountain Lion stripped out.

Go here and download 2.7.2+. Install it, and after it’s done, fix the symlink it makes:

ln -s /opt/X11 /usr/X11

When XCode download is done, launch it and go to Preferences, Downloads tab, and install the Command Line Tools. When it finishes, we are almost ready to brew. Before we do, let’s have XCode tell everyone where the tools are (this tip is from Get Mountain Lion and Homebrew to Be Happy).

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

Open up a new shell to make sure everything is loaded from scratch, and check that homebrew is good to go:

brew doctor

Fix the stuff it complains about until it doesn’t.

Now let’s get git:

brew install git

When I ran brew doctor, I complained:

$ git config --global core.autocrlf input

$ brew doctor

Warning: Suspicious Git newline settings found.

The detected Git newline settings will cause checkout problems:

  core.autocrlf = input

If you are not routinely dealing with Windows-based projects,

consider removing these settings.

Alternatively run:

`git config -f /usr/local/.git/config --add core.autocrlf false`

Warning: Suspicious git origin remote found.

With a non-standard origin, Homebrew won't pull updates from

the main repository. The current git origin is:

  

Unless you have compelling reasons, consider setting the

origin remote to point at the main repository, located at:

  https://github.com/mxcl/homebrew.git

Brew did not like  core.autocrlf = input

 core.autocrlf = false worked better...

$ git config --global core.autocrlf false

$ brew doctor

Warning: Suspicious git origin remote found.

With a non-standard origin, Homebrew won't pull updates from

the main repository. The current git origin is:

  

Unless you have compelling reasons, consider setting the

Still have problem with ORIGIN

$ brew --config

Already up-to-date.

$ brew doctor

Your system is raring to brew.

Looking good...

$ brew --config

So, it seems that installing Home Brew does not get the most latest version, which was needed b/c they recently fixed the ORIGIN bug.
