[netCDF #QTB-782234]: problem about make check install netCDF for I/O parallel support


I'm afraid I'm not going to be as much help as I'd like with this; I don't have 
access to a machine where I can recreate this issue, and I am not an MPI 
expert.  Are you able to confirm that the cause is not one of the two reasons 
it lists, e.g. is `mpd` running and was it started with a console (-n) option?

If this is the case, I'm afraid I can't think of another reason why such a 
specific error would be given.  If mpd is not running, or was started 
incorrectly, this might be an issue your systems administrator will need to 
address; I'm afraid I can't say for certain as I'm  unfamiliar with mpd.

I'm very sorry that I can't be more help,
