I've managed to find a test case for me that sounds much like the
problem described in this bug report.
It popped up for me while installing Task::Kensho during Makefile.PL.
Reducing that Makefile.PL to the simplest case that still fails gives me
this:
#!/usr/bin/perl
use strict;
use warnings;
use inc::Module::Install;
requires "Devel::NYTProf";
requires "Term::ProgressBar::Simple";
auto_install;
__END__
include /tmp/inc/Module/Install.pm
include inc/Module/Install/Metadata.pm
include inc/Module/Install/Base.pm
include inc/Module/Install/AutoInstall.pm
include inc/Module/Install/Include.pm
include inc/Module/AutoInstall.pm
*** Module::AutoInstall version 1.03
*** Checking for Perl dependencies...
[Core Features]

*** Module::AutoInstall configuration finished.
