I noticed that the INTERNALS document claimed that tools were maintained
to be compatible wirh perl version 4.
Intrepidly I downloaded the tarball for perl 4.0.36 (from 1993) and,
with a couple of tweaks, was able to build it. (The Configure script
listed many now-obscure operating systems, but no GNU/Linux - presumably
still in nappies at that stage.) Sure enough, perl4 barfs on modernisms
such as "my" and "BEGIN" in chksource.pl and runtests.pl.
I can't imagine any development platform is really still using perl4
these days, so I suggest conservatively moving the requirement forward
to version 5.004 (from 1997).

Subject: [PATCH] Require a less ancient version of perl
The INTERNALS document suggested that compatibility should be
maintained with perl version 4, but this was untrue - scripts such as
chksource.pl and runtests.pl use perl5-isms.
