Mountain Lion install rvm ree-1.8.7

Question

I tried following this other answer, but I get the following problems:

$ export CPPFLAGS=-I/opt/X11/include
$ CC=/usr/local/bin/gcc-4.2 rvm reinstall ree-1.8.7
/Users/username/.rvm/src/ree-1.8.7-2012.02 has already been removed.
/Users/username/.rvm/rubies/ree-1.8.7-2012.02 has already been removed.
No binary rubies available for: osx/10/x86_64/ree-1.8.7-2012.02.
Continuing with compilation. Please read 'rvm mount' to get more information on binary rubies.
You requested building with '/usr/local/bin/gcc-4.2' but it is not in your path.

Is there something else I am doing wrong? I am using the October release of Command Line Tools from Apple, if that helps...

Did you look to see if `/usr/local/bin/gcc-4.2` is actually there? — Mark Reed, Oct 16 '12 at 21:28
Here is what I see when I run 'rvm mount': "The given paths '' either do not point to a ruby installation or are already mounted." — Chris Butler, Oct 17 '12 at 04:25

Ok, after some discussion on the other answer I got it to work like this...

First, install brew then do this:

brew tap homebrew/dupes
brew install apple-gcc42

Then the rest of the solution will work:

export CPPFLAGS=-I/opt/X11/include
CC=/usr/local/bin/gcc-4.2 rvm reinstall ree-1.8.7

Mountain Lion install rvm ree-1.8.7
