So, if it works from the command line, it's something in the
environment.  What is the value of $PATH?

Was that verbose logging or debug logging?

May I see your pqact.conf entry?  And, also please send me the command
as you executed it from the command line.

If all else fails, my next step would be to put some trace statements
that write to a file in nexradII_bz and see how far it's getting.  From
what I've seen we're unable to  determine if the executable is even
getting started or not, is that right?
