emacs.pkgs.melpaBuild: package-build: 2018-10-05 -> 2021-04-13
I think this is due an update.  I've chosen to update to the latest
version that has been merged into Melpa.

Unfortunately we now need to hack around it trying to run VCS
commands.

My Emacs configuration with thirty-something leaf packages seems fine
after the rebuild.
