Here is what I did to my 2013 macbook (OSX 10.10.1) to get the developing environment I want.

Homebrew

Install:

/usr/bin/ruby -e "$(curl -fsSL https://raw.github.com/gist/323731)"

Result:

Warning: The following *evil* dylibs exist in /usr/local/lib

They may break builds or worse. You should consider deleting them:

/usr/local/lib/libfuse.2.dylib

/usr/local/lib/libfuse_ino64.2.dylib

==> Installation successful!

Now type brew help to familiar yourself with homebrew

tmux

depends on libevent, install by homebrew:

brew install libevent

Font

get them from here

Used ones: * Bitstream Vera Sans Mono * Monaco

pip, virtualenv, virtualenvwrapper

sudo easy_install pip
sudo pip install virtualenv
sudo pip install virtualenvwrapper

to use a specific version of python in a virtual environment:

virtualenv --python=/usr/local/bin/python2.7 python27

to activate:

source python27/bin/activate

to exit, in the virtualenv, type deactivate

to remove a virtual environment, simply delete the created folder:

rm -rf python27

autojump

zsh

oh-my-zsh

Install gcc 4.8 with colorgcc and ccache

brew tap homebrew/versions
brew install gcc48

download colorgcc.pl from here save it to /usr/local/bin

delete gcc and g++ links in /usr/bin, then

sudo ln -s /usr/local/bin/colorgcc.pl gcc
sudo ln -s /usr/local/bin/colorgcc.pl g++

brew install ccache

create /usr/local/bin/ccache-gcc.sh and /usr/local/bin/ccache-g++.sh

then

ccache /usr/local/bin/gcc-4.8 "$@" 

ccache /usr/local/bin/g++-4.8 "$@" 

edit colorgccrc to make it use cache

vi ~/.colorgccrc

change the following line:

gcc: /usr/local/bin/ccache-gcc.sh

g++: /usr/local/bin/ccache-g++.sh

Haskell

brew install haskell-platform

Note: the gcc command on Mac OSX is no longer a real gcc, it's just a gcc front end for clang, so even it mentions gcc version 4.2.1, it's actually clang-600, which has all the C++11 features you need supported.
