Temporarily set gcc to point to GCC 4.2 instead of LLVM

gistfile1.sh

# This gist is a small recipe for temporarily making your Lion box point to GCC 4.2 instead of LLVM, like for things such as Ruby, which isn't yet made to compile on the newer and better LLVM

# First make sure you've installed Command Line Tools from Xcode 4.3 preferences

cd /usr/bin/
ls -l *gcc*

# Important: Only do this if gcc is a symlink to llvm! if not, this gist isn't the way to go! :)
# It should look like this:
# lrwxr-xr-x  1 root  wheel      12 Mar 22 14:12 gcc -> llvm-gcc-4.2
# See how gcc is just a symlink to LLVM?

sudo rm gcc
sudo ln -s gcc-4.2 gcc

# do your ruby shit or whatever. then change things back

cd /usr/bin/
ls -l *gcc*
sudo rm gcc
sudo ln -s llvm-gcc-4.2 gcc
