Instructions for OS X outdated

[trein]

Hi,

The installation instructions for OS X are outdated on setup.md. If you perform Tesseract install using Brew formula, the prefix in setup.py should be set to prefix="/usr/local/Cellar/". Also, other adjustments must be done in order to correct the path for Tesseract and Leptonica (draft below):

tesseract_module = Extension('_tesseract',
                  sources=['tesseract.i','' 'main_dummy.cpp','fmemopen.c'],
                  swig_opts=["-c++", "-I"+inclpath('tesseract/3.02.02/include/tesseract'),
                          "-I"+incl,
                          "-I"+inclpath('leptonica/1.69/include/leptonica')],
                  include_dirs=['.',inclpath('tesseract/3.02.02/include/tesseract'),
                          incl,
                          inclpath('leptonica/1.69/include/leptonica')],
                  libraries=['stdc++','tesseract','lept'],

                  )

However, even if this monkey patch, the installation script fails.
