No. If GISBASE isn't defined at that point, try:

	set PYTHONPATH=%OSGEO4W_ROOT%\apps\grass\grass-6.5.svn\etc\python;%PYTHONPATH%

PYTHONPATH shouldn't include the directory where Python itself is
installed. PYTHONHOME is used for that, e.g.:

	set PYTHONHOME=%OSGEO4W_ROOT%\apps\Python25

This error may be caused by a broken Python installation or a missing
or incorrect PYTHONHOME setting.
