if you look at wscript, you'll see you need to enable mpi:

@teto
Thanks for your reply !

I just run these command:
./waf distclen
./waf configure --with-ns3=../../build --enable-mpi
./waf build

but when I run this:
mpirun -np 2 ./waf --run dce-mpi-udp

I got these erro:
msg="Can't use distributed simulator without MPI compiled in", file=../src/mpi/model/granted-time-window-mpi-interface.cc, line=185

probably ns3 was compiledwithout mpi support.
