To build you will need:
This is all part of a current stable Debian distribution for example
First enter protos subdir and execute ./generate_protos.sh second execute make in src subdir.
The scripts subdir contains a small tool to set up a tun device for phantom. The source in there is modeled after Jeff Dike's tunctl program and explicitly not part of phantom.
See src/test for the leftovers of my test setup network configuration - This should give you some pointers on how to set up your own network for testing. There is no easy way to do this yet.
For general information about Phantom and its implementation you can find some resources in the docs subdirectory and some further information is provided by the links below:
