Steve,

It does indeed appear that the libgrass version of the code is being used.
I suspect that both versions of the code have been compiled and linked in.
I would suggesting doing a "make clean" and then make again.  If you
reconfigured and rebuilding without a make clean, it is likely that the
old grassdataset.o would still be handing around in the gdal/frmts/o
directory or libgdal.a.

The logic within the gdal/frmts/grass directory is controlled by the
GRASS_SETTING variable which should be either "libgrass" or "grass57+".
You might want to check GDALmake.opt to see if the variable is set properly.

Best regards,
