The error is not passed as an argument to your die handler, but is in $@.

Why shell out just to print an error message?

my $message = $@; if( open my $log, '>>', 'log.err' ) { print $log $message; } else { warn "Couldn't write to 'log.err': $!"; warn $message; };

Also, your __DIE__ handler will also be invoked from within eval { ... } blocks, which is most likely only confusing to you. You should check $^S to see if eval is currently running:

return if $^S; # we are within an eval block
