This indicates that gdal-config doesn't understand the --dep-libs
switch. That may or may not be a problem.

Search for GDALOpen the config.log file. That may provide some clues
as to the exact error. The most likely problem is that one of the
libraries which GDAL requires (and there may be a lot of them) isn't
found.

These switches don't exist. The header and library directories for
GDAL are determined by running "gdal-config --cflags" and
"gdal-config --libs" respectively.

Essentially, the gdal-config script has to provide accurate
information on how to use the GDAL library. If the information is
inaccurate, attempts to use the library will fail, and you won't be
able to build GRASS (GDAL is a mandatory dependency for GRASS 6.x).
