Current GDAL 1.9.0-1 package in Archlinux/Community will produce following error message
when handling GRIB2 format data:
<code>ERROR 4: `/vsimem/work.jpc' not recognised as a supported file format. dec_jpeg2000: Unable to open JPEG2000 image within GRIB file. Is the JPEG2000 driver available?Driver: GRIB/GRIdded Binary (.grb) </code>
Because the gdal package in Archlinux/Community is out of data,
one can fix this by replace gdal with gdal-svn package in the AUR
