I just downloaded 2.20.0 and 2.21.0 and both contain GhostScript in
version 9.21. You're seeing 9.26 probably because the gs executable is
linked dynamically and will use the libgs.so.9 it finds first. By
default this is in /usr/lib/ which comes from your distribution. When
instead using the wrapper script provided by the installer and put into
bin/, you will get the correct version because it sets some magic
environment variables.

So the "correct" way to determine the version is
LD_LIBRARY_PATH=lilypond/usr/lib/ ./lilypond/usr/bin/gs --version
which returns 9.21

To address the original problem you should invoke lilypond via the
wrapper script /usr/local/lilypond-2.21.0/bin/lilypond
instead of using the the directly binary from
/usr/local/lilypond-2.21.0/lilypond/usr/bin/lilypond.
