Setting up the development environment on Mac

Note: if you are a Macports user, see the comments at the end of point 2.

1. Installed homebrew using the instructions https://github.com/mxcl/homebrew/wiki/installation. Please note that if you have installed Macports before, Macports and Homebrew are not friends. Macports will need to be completely uninstalled from your computer. You will also need to have already installed Xcode.

2. Installed MySQL, Python, Pip, virtualenv, virtualenvwrapper, gettext

    #installing mysql  
    brew install mysql 
    
    #installing Python prerequisites per http://youshoulddoityourself.blogspot.com/2010/11/test.html 
    brew install readline sqlite gdbm 
    
    #installing Python 
    brew install python --universal --framework 

    #installing gettext (required for translation)
    brew install gettext

    #installing PIL (for handling images)
    brew install pil

For Macports users, the commands are:

    # Installing MySQL
    sudo port install mysql5

    # Installing readline, gettext, etc.
    sudo port install sqlite3
    sudo port install readline
    sudo port install gettext

I then had to manually add /opt/local/lib/mysql5/bin to my PATH so that this line:

    pip install -r requirements/compiled.txt

from the standard installation instructions would be able to find mysql_config.

3. At this point, I followed the advice in the blog post above and /etc/paths so that /usr/local/bin was at the top of the file. Then, I installed pip.

    #installing pip 
    #The Python formula installs Distribute 0.6.15, which provides easy_install. pip can then be installed with:
    easy_install pip
    
    #using pip to install virtualenv and virtualenvwrapper 
    pip install virtualenv 
    pip install virtualenvwrapper

4. Set up symlink for virtualenv in the bin directory

5. Added the virtualwrapper script to my .profile file (could have done .bash_profile or .bashrc instead)

    export WORKON_HOME=$HOME/virtualenvs
    source /usr/local/Cellar/python/2.7.2/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh

After this point, I was able to follow the Lernanta instructions the start with "Once installed, create your virtual environment for lernanta and install the dependencies."
