Will be easier if you have RVM installed (https://rvm.io) just cut and paste on the commandline for ruby 2.0.0
curl -L https://get.rvm.io | bash -s stable --ruby
Then run the build script
./build
To run you can simply type
reogeo
at the command line and all the *.kml files will be converted to android resource arrays as appropriate for use by LocationProvider our mock Location service.
