That would disable the possibility to run with 6 or 7.

QGIS is installed in /osgeo/QGIS/ and
/osgeo/QGIS/grass/config/default.qgc exists?
The path is constructed as QgsApplication::pkgDataPath() +
"/grass/config/default.qgc".
For now, I think that you have to install QGIS to get it working (or
do some dirty trick like symlinks from /osgeo/QGIS/grass/).

Exactly.
