Well assuming that $key = 'Varbind' and that $value is an array ref containing each part of the id, then you can use join: 
print "$key: ".join('.',@$value)."\n";

When you use an array in a string (like "@a"), perl translates this internally into join($", @a), one can see this if you turn perl's bytecode back into source code using B::Deparse.
