I'm trying to install boost-python on OSX using brew install --build-from-source --fresh -vd --with-python3 boost-python but during the installation, the python detected is 2.7:

On my system, python is 2.7 whilst python3 is 3.5. I wonder why ./bootstrap uses --with-libraries=python --with-python=python rather than python3.
Any thought appreciated.
