I think this is the more relevant requirement, the above build even links to an audio library...

Of course, we can do even better these days

    $ ldd /opt/sublime_text/sublime_text | wc -l
    15
    $ ldd /home/tmk/.local/share/umake/ide/visual-studio-code/code | wc -l
    84

And I'm not sure ldd even captures all the libraries these things load.

Things are better still when one stops looking at shared libraries and starts looking at run-time remote procedure call dependencies.

The GNOME editor, a "small and lightweight text editor" according to the blurb and its reviews by some clearly incurious reviewers, requires that a per-user/per-login Desktop Bus broker be running and also (on my machine) that the following Desktop Bus servers be running: at-spi-bus-launcher (which runs another Desktop Bus broker), api-spi2-registryd, dconf-service, gvfsd, gvfsd-udisks2-volume-monitor, gvfsd-afc-volume-monitor, gvfsd-goa-volume-monitor, gvfsd-gphoto2-volume-monitor, and gvfsd-mtp-volume-monitor.

Normally, it behaves like WIN16 programs used to behave: invoking the editor a second time simply sends a D-BUS message to the already running first instance to tell it to open another document and then exits that second invocation. If you want to start up a true second separate instance, one way to do so is use dbus-run-session to start it up with a private Desktop Bus broker of its own. Of course, doing so starts up second instances of all of the aforementioned D-BUS servers as well.

This is not "small and lightweight".

nvi vs. X11 emacs? Isn't that a bit like comparing uemacs to gvim?

This isn't comparing X11 emacs to vi, it's emacs (built w/ a no-x11 switch) on NetBSD compared w/ native nvi. If this were an X11 enabled binary, you'd see links to various X11 libs and GUI toolkits, similar to this xterm:
