== Install Python ==

1. You will propably need the GIS features of Eden. Before you proceed install the GDAL framework
 * http://trac.osgeo.org/gdal/wiki/DownloadingGdalBinaries

2. You also need to install some modules of python
{{{
STATIC_DEPS=true sudo easy_install lxml
sudo easy_install shapely
sudo easy_install reportlab
sudo easy_install xlwt
sudo easy_install pyserial
sudo easy_install tweepy
}}}

3.In case you want to use PostgreSQL - PostGIS (I assume you already installed the spatial modules before)
 Install the one clickInstaller sponsored by EnterpriseDB PostgreSQL and select also installation of postgis.
 Then based on this article http://schwuk.com/articles/2009/09/10/psycopg2-on-os-x install the python database driver 
{{{
sudo easy_install pip
PATH=$PATH:/Library/PostgreSQL/8.4/bin/ sudo pip install psycopg2
defaults write com.apple.versioner.python Prefer-32-Bit -bool yes
}}}
 without the last you will not be able to see available the PostgreSQL driver when web2py launch

=== Trouble? ===
 * {{{lxml}}} can give trouble on OS X.  Try:
  * {{{STATIC_DEPS=true sudo easy_install lxml}}} (adapted from [http://blog.ianbicking.org/2008/12/10/lxml-an-underappreciated-web-scraping-library/ this blog post])
  * remove other {{{libxml2}}} versions, such as may have been installed by {{{fink}}} or !MacPorts - ONLY works in unmodified python setup. In case you have modified your python you must link some how the python directory with /frameworks/python otherwise lxml will not being found(not tested)
