I alredy suggested that, but it has been ignored. Let's try again.

If you want to install in /usr/local or wherever else:

python3 -m venv --system-site-packages --without-pip /usr/local/
waf configure --python=/usr/local/bin/python3

and all should work (assuming that waf does the right thing when a
python interpreter is specified at configure time, ie replace the right
executable on the shebang of the installed scripts).

Cheers,
