Eric,

The log message:
>[6405] 030806/0906 [DCGRIB -51] can't open grib tables [NA -51], set
>GEMTBL  

Means that you don't have $GEMTBL defined in the LDM environment, and 
have not defined it using the -e GEMTBL=path option to the dcgrib2 decoder.
Or, you have a typo in your GEMTBL path for that invocation.

The decoder needs that environmental variable to find its tables.
