I suspect it is related to:
https://lists.gnu.org/archive/html/bug-automake/2017-06/msg00003.html

The problem is how perl is handling regex escaping where a newer perl
causes an error when an older perl caused a warning. Since we are kind
of stuck with an older automake, you should install an older perl.
Apparently, something before 5.26.0 should work I guess.
