This is a problem you'll run into each time you will open a NITF image whose 
imagery is compressed as a JPEG2000 codestream. Compiling --with-jasper might 
help, but if your image is big, it might not work since jasper reads the whole 
image into memory. If you run into this memory problem, you might use OpenJPEG 
2 instead (provided you use GDAL 1.10), or else one of the proprietary 
implementation.

If gdalinfo can open it, then it should work with r.in.gdal.
