You will need to install Google's protobuf library to run this program. It is used to parse the .build.conf file.
This binary is known to work on Slackware64 13.37 and 14.0 and RHEL ES 5. Other x86_64 Linuxes may also be able to use it.
This binary is for Intel-based Macs running Mountain Lion (10.8). It is not known if it will work on Lion (10.7). It definitely will not work on Snow Leopard (10.6).
MacPorts users: you can run
sudo port install protobuf-cpp to get Protocol Buffers
installed on your machine.
brew install protobuf should get things going.
