20011204: Write Errors in Gempak pqact entries

Adam,

You want your GEMPAK decoded data to go to /data1/gempak/...

The pqact.conf entries as they stand will be trying to write
the data to the data/gempak/ directory under the ~ldm location.
the pqact.conf entries are relative to the ~ldm user account.

If you don't have a symbolic link from ~ldm/data/gempak to /data1/gempak,
then that would explain the error messages you have below.

The dcgrib2 decoder will create the necessary directories(eg model/)
under that location (decoders I wrote here will do that). You need to 
create your /data1/gempak/logs directory (specified by the -d option in 
the decoders). You will also have to create the directories for the dcmetr, 
dclsfc, dcmsfc etc. decoders (decoders written at NCEP need to have the 
directories
created for them) if you haven't already.
