I believe you'll encounter that error everytime that $dbh leaves scope.. What I normally do to get around this is check the "environment" first, after I've verified my program has all the options and info needed to run, I'll open up a global $DBH, and then I'll do an end block like:

END {
    $DBH->disconnect;
    # whatever else you want to clean up neatly
}

which I guess is a cheap hack, but works..
