Run the master, then the slaves to join the master, then the commands.

gproc m <unix-domain-socket>, e.g. gproc m /tmp/g

Note the socket number:

start  slave: 
It has to run as root due to the private name space setup. 
sudo ./gproc s  tcp4

Then run a command: 
./gproc  -f /etc/hosts,/tmp -localbin e  /tmp/x tcp '1' /bin/ls -ld

and it should all work.
