Some updated Portfiles for geo application via MacPorts.
Rakefile via Jeff Hodges, just cd to the ports directory and run:
$ rake
This will generate the PortIndex, install a new MacPorts source pointing at this directory, and set up a Git post-commit hook to regenerate the PortIndex any time you commit Portfile changes.
Now you can sudo port install libspatialite to install the latest
libspatialite etc. For a list of available local ports, try rake list.
To manually update the PortIndex (or to fix the Git hook, or the sources list),
just run rake again.
