[gdal-dev] GRIB2 file produces None on opening

I have the same problem.  I just installed 1.5.2 version on Linux. When I do:
gdalinfo --formats | grep GRIB

Nothing came out.  Also when I do:
gdalinfo abc.grb I got: not recognised as a supported file format

My grb file is GRIB2 format.  Do we need to download the GRIB driver 
before the installation?
