Subject: [PATCH] Ignore mismatched versions between Carp and Carp::Heavy if
 the version discrepancy does not actually lead to broken code

Carp::Heavy's guts were merged into Carp in 1.12. After this point, if a
different version of Carp::Heavy is loaded than Carp, no harm will be done and
the error can be ignored.

$VERSION can't be lt 1.12, having been set earlier in the same file to a
higher version. $cv lt 1.12 mishandles the undef case. $cv ne $VERSION
is redundant with the lt check. String comparisons are not correct for
inequality comparisons of version numbers. You want something like

if (($Carp::VERSION || 0) < 1.12) {
my $cv = defined($Carp::VERSION) ? $Carp::VERSION : "undef";

This looks sane to me, added as a 5.21.1 blocker since blead is frozen.
