With the current release, you don't need to do anything special to build with networking support.  If your build environment has the required libpcap components installed, then a simple make will build a network capable binary.

The first few lines of the build output will describe what capabilities and/or host features are available to enable functionality in the simulator(s) being built.

In your case, you invoked make with USE_NETWORK=1.  This will produce binaries which have static networking built in.  These binaries will require that libpcap be available on the system you run it on, but they won't run at all if libpcap components aren't on the executing system.  If you build without the USE_NETWORK=1, then the binaries produced will also produce useful networking if the running system has libpcap installed, and if it isn't installed, then the binaries will run, but networking won't be available.
