GrADS DODS Win XP -> Linux

[Derek Goring]

I'm moving from Win XP to Linux with my GrADS DODS routines.
 I'm a newbie in Linux, but I've managed to install gradsdods OK and once I set GIDDIR using export, it seems to open OK.  However, when I try to open a file, this is what I get:

 sdfopen http://nomad3.ncep.noaa.gov:9090/dods/gfs/rotating/gfs_12z
 Scanning self-describing file:  http://nomad3.ncep.noaa.gov:9090/dods/gfs/rotating/gfs_12z
 nc_open failure:
 Invalid argument
  does not exist or is not a netCDF file.s/rotating/gfs_12z

 Couldn't ingest SDF metadata.
 If this was an HDF-SDS file, try gradshdf.

 Yet this same command works OK in Win XP.
 Can anyone suggest where I'm going wrong?
