Those are the intended methods.

That means ~/bin comes before the system directories in your $PATH
which is fine, as is the opposite. I define aliases lily and lilyo
to point to the respective versions; saves keystrokes!

Pretty much. If you list ~/bin/lilypond, you'll see something like

#!/bin/sh
me=`basename $0`
export LD_LIBRARY_PATH="/home/david/lilypond/usr/lib"
exec "/home/david/lilypond/usr/bin/$me" "$@"

When you ran lilypond/usr/bin/lilypond, the whole of the
/home/david/lilypond/usr/lib tree was ignored and it tried to
use your system versions instead.

(Using PDFs is fine.)

Cheers,
David.
