The 6.x build system no longer generates the unversioned symlinks,
which the configure script requires.

This has long been the case for the 7.0 build system, but the
gdal-grass configure script explicitly checks for the versioned names
for 7.0.

You could just generate the symlinks yourself, e.g.:

	cd /usr/local/grass-6.5.svn/lib
	for file in libgrass_*.so ; do ln -s $file ${file%.6.5.svn.so}.so ; done
