[neteler at pgis_north ]$ alias python=python3.4
[neteler at pgis_north ]$ export GRASS_PYTHON=python3.4
[neteler at pgis_north ]$ grass71
Cleaning up temporary files...
Starting GRASS GIS...
...

GRASS 7.1.svn (nc_spm_08_grass7):~ > echo $GRASS_PYTHON
python3.4


GRASS 7.1.svn (nc_spm_08_grass7):~ > v.rast.stats
