I had a problem when I tried to install version 0.10.2 of therubyracer gem on Mac OS X Yosemite, so I searched and I tried different solutions, and the one it works for me was this:
brew tap homebrew/dupes
brew install apple-gcc42
export CC=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/gcc-4.2
export CXX=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/g++-4.2
export CPP=/usr/local/Cellar/apple-gcc42/4.2.1-5666.3/bin/cpp-4.2
brew uninstall v8
gem uninstall libv8
gem install therubyracer -v '0.10.2'
Any place where I can pick the code of this tip?
