Can not brew install gcc48 on Mac

Who have already successfully used homebrew to install the latest GCC 4.8.1 on Mac OS X(10.8.4)? I am always stuck when it runs to "make bootstrap".

$brew install gcc48 ==> Downloading ftp://gcc.gnu.org/pub/gcc/releases/gcc-4.8.1/gcc-4.8.1.tar.bz2 Already downloaded: /Library/Caches/Homebrew/gcc48-4.8.1.tar.bz2 ==> ../configure --build=x86_64-apple-darwin12.4.1 --prefix=/usr/local/Cellar/gc ==> make bootstrap

Can you install g ++ on Mac?

Installing G++ on a Mac. This section is intended to get you quickly started with C++ programming on your Mac. We'll be installing GCC 4.8. 1 and GDB through a tool called Homebrew.

I've just done precisely this install. Be patient – that step does take a long time and is very CPU intensive. On my (admittedly old) Macbook Pro it took over 30 minutes to complete. I suggest you try running it again and just leaving it until it's done.
