to use standard python3 without addons, in addition to installing some tools just do:

./configure MACOSX_DEPLOYMENT_TARGET=<TARGET> --prefix=/Library/Frameworks/Python.framework/Versions/<VERSION> --enable-shared
make
make install

and there are no conflicts with other packages like brew

I always installed ruby without using rbenv; now on Sierra I'm using 2.4.1p111

I prefer to use the base terminal and then customize it; but if you want to use iterm2 there is already the version ready for OSX without going through brew
