Thanks for the patch.
However, that test should exit 77, and hence merely be skipped,
when /usr/bin/perl does not exist.  Please run it manually,
to see what's going wrong:

  PATH="$PWD/build-aux:$PATH" bash -x gnulib-tests/test-update-copyright.sh

when I simulate having no /usr/bin/perl by
changing that script to attempt to use /usr/bin/no-perl
in the first test, it detects the problems and does this:

    $ PATH="$PWD/build-aux:$PATH" gnulib-tests/test-update-copyright.sh
    gnulib-tests/test-update-copyright.sh: skipping this test;
    your system has insufficient support for Perl
    $ echo $?
    77
