can't start pvm console/daemon

[Marc van Woerkom]

Hi,

soon I need to write a pvm application destined for a 
linux cluster at university.

It would be very nice, to be able to already develop on my 
FreeBSD 6.0 laptop.
(I already saw phk's hint in the cvs log to simulate 
  several pvms using FreeBSD jails) 

But just setting PVM_ROOT to /usr/local/lib/pvm and 
starting pvm won't work.
I don't see the console, there seem to be some socket 
related problem.

Do I need to enable certain ports to run pvm?

Regards,
Marc
