You need to follow the directions in the python3-setuptools-opt README,
which will have you set a variable in the SlackBuild requiring it to point
it to the python packages residing in /opt/, namely:

PYVER=$(python3 -c 'import sys; print("%d.%d" % sys.version_info[:2])')
export PYTHONPATH=/opt/python$PYVER/site-packages
