My naiive approach (I'm a newbie) would be to check two lines in a row, something like...

my $prev;
while (<DATA>) {
    if (/^\s*$/ && $prev =~ /^\s*$/) {
        # Two blank lines in a row found
    }
    $prev = $_;
}

It doesn't look a particularly Perl way to do it though, so I guess my inexperience is showing.
