Bad side-effect with a third party module in site_perl.
Strange that I didn't see this in my tests, because I tested over
thousand CPAN modules with this release.
Oh, I see, I reported that it failed on June 5.

$ cpan DateTime
requires DateTime::Locale

DateTime::Locale cannot be installed because of this error,
but since you upgraded perl we have to fix DateTime::Locale now.

Oops. This seems to affect more modules.
Params::Validate with type => SCALAR seems to be broken.
  http://rt.cpan.org/NoAuth/ReportBug.html?Queue=Params%3A%3AValidate

I have to go now, but will provide a patch soon.
As workaround I would disable the validation in DateTime::Locale::_register
but this also doesn't work as expected.

    if (! defined $p{id} or !$id) {
	# cygperl5 error in Params::Validate?
	#warn "Broken Params::Validate. Given ".join(",",@_);
        $p{id} = $_[0];
        $p{en_language} = $_[1];
	my @keys = qw(en_script en_territory en_variant native_language
native_script native_territory native_variant class replace);
	for my $i (2 .. @_) {
	    $p{$keys[$i]} = $_[$i];
	}
    }
