Get Mountain Lion and Homebrew to Be Happy

Get Mountain Lion and Homebrew to Be Happy

1) Install XCode 4.4 into /Applications

Get it from the App Store.

2) Install Command Line Tools

In XCode's Preferences > Downloads you can install command line tools.

[insert screenshot]

3) Let Everyone Know Where XCode Is

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

4) Install X11

Visit http://xquartz.macosforge.org/trac/wiki and download and install 2.7.2+.

You will need to fix the symlink it makes:

ln -s /opt/X11 /usr/X11

5) Install non-llvm GCC

brew tap homebrew/dupes
brew install apple-gcc42

6) Reinstall your brews

brew list

Will tell you what you need to check. Try out everything one by one and when one doesn't work brew remove it and then reinstall it. If the install doesn't work, try brew install it --use-gcc to prevent llvm from getting in the way.

Things that gave me issues that I had to remove and install:

  • macvim
  • imagemagick
  • ghostscript

You might need to install libxml2 and link it manually to make sure you don't get the wrong xml2-config if your path:

brew install libxml2  
brew link libxml2

Run brew doctor and fix anything it tells you.

You may also need to symlink gcc for certain ruby gems and other stuff like that:

sudo ln -s /usr/bin/gcc /usr/bin/gcc-4.2

You are good to go.

Random links that may help

Ruby Notes

1.8.7

Install with

CPPFLAGS=-I/opt/X11/include rvm install 1.8.7

Libv8 needs to be manually installed with

RUBYOPT=-rrubygems gem install -v [version] libv8

Rmagick

Depends on libtool. If installed before upgrade, this must be reinstalled.

brew uninstall libtool
brew install libtool
gem install rmagick
