thanks Glenn. I also noticed the aparent reference to the previously
installed emacs version and figured it looked wrong. I tried manually
removing the previous installed version of Emacs from /usr/local/* and
then did

make extraclean
./autogen.sh
./configure
make bootstrap

and now get a segmentation fault i.e.

Loading bindings (source)...
Fatal error 11: Segmentation fault
make[3]: *** [Makefile:309: emacs-lisp/macroexp.elc] Segmentation fault (core 
dumped)
make[3]: Leaving directory '/home/tim/git/emacs/lisp'
make[2]: *** [Makefile:850: bootstrap-emacs.pdmp] Error 2
make[2]: Leaving directory '/home/tim/git/emacs/src'
make[1]: *** [Makefile:449: src] Error 2
make[1]: Leaving directory '/home/tim/git/emacs'
make: *** [Makefile:1147: bootstrap] Error 2

This was on a virtual machine running Ubuntu Mate 21.04 and which built
fine earlier this week.

If make extraclean and make bootstrap doesn't resolve this issue, what
needs to be done to get Emacs to build?
