If python3 with all required packages is already installed on the system,
there is a simpler solution than virtualenv:

mkdir ~/bin_p3
ln -s /usr/bin/python3 ~/bin_p3/python

# make python3 the default python interpreter
export PATH="~/bin_p3:$PATH"

compile GRASS and run GRASS with these PATH settings

alternatively, the shebang in GRASS *.py files can be changed to python3
(should be changed to python3 according to Python developer's Guide PEP394)
