Hmm. The GTK SourceView control has been a bit of a pain in previous
porting jobs. You may end up needing to build something from source.
Sorry :(

No idea. If you're talking about the way that "python3 -m pip install
..." is preferred over "pip3 install ...", then that's due to the
possibility of having multiple Pythons installed; but if you're using
a virtual environment, or you're confident you have full control over
your setup, you can just use the shorthand.

That's still using pip, though. Just not using /usr/local/bin/pip (or
equiv) to invoke it.
