Mac OSX Build

Notes on successfully building the Retriever on OSX.

I just successfully built the Retriever on OSX 10.9 using the following process. The notes are going to be comprehensive for the moment since we've had difficulty with this in the past. I am also keeping the exact order even though it probably doesn't matter.

1. Install Homebrew
2. Install Xcode
3. Install Python brew install python
4. Install the Xcode command line tools xcode-select --install
5. Install wxPython using Homebrew brew install --python wxmac --devel.
6. Make brew's Python the default echo export PATH='usr/local/bin:$PATH' >> ~/.bash_profile
7. Install xlrd via pip pip install xlrd. No sudo is necessary since we're using brew.
8. Install py2app via pip pip install py2app.
9. Clone the Retriever git clone git@github.com:weecology/retriever.git
10. Switch directories cd retriever
11. Standard install python setup.py install
