I am trying to setup an isolated python virtualenv to work on GIS projects on my Mac OS X. Sounds like I will need to install the GEOS, PROJ, GDAL/OGR from the kyngchaos site here http://www.kyngchaos.com/software/frameworks and not easy_install it into my virtualenv. Is that accurate?

The downloads available on kyngchaos are pkg installers and not just an egg or bdist of python modules. So, I am not very sure as to what else the installer is doing to the environment other than just copying files to /Library/Framework/geos.framework folder.

How would I go about installing a specific version of GEOS, PROJ, GDAL/OGR into my new python virtualenv? I would appreciate your help/suggestions on this issue.

Thank You, Vish
