I'm using virtualenv to isolate python2:

$  virtualenv --system-site-packages -p python2.7 env-python2

then I have to activate the virtualenv with:

$ source ~/envs/env-python2/bin/activate

I just put an alias on .bashrc:

alias activate_python2='source ~/envs/env-python2/bin/activate'
alias grass70='activate_python2 && python2
~/src/gis/grass/grass_trunk/bin.x86_64-unknown-linux-gnu/grass70

therefore before compile grass I have to:

$ activate_python2
$ make

I'm curious how do you solve it? may be there is a best way... :-)

Best regards
