That is expected: the MC barostat does not ever compute the internal
pressure, and so prints out "0.0" in that slot. It would be less
confusing if it simply didn't print anything, but such a change would
break lots of programs that parse mdout files.
You can follow the volume fluctuations by printing the "VOLUME" entry as
a function of time. (Or, what is equivalent, but maybe easer to
understand, follow the "Density" values.)
