I'm unfamiliar with the syntax you're using. As far as I know, $HOST is for the host of the machine on which the MySQL server runs. Also, as far as I know, the server determines your hostname automatically during connection, checking it against the grant table.

Privileges to connect to a MySQL server exist independently of the user/group of the script -- they're determined by the hostname from which to connect to the server and the username and password provided when connecting.

With all that said, I usually use a connect string something like: 

use DBI;
my $host = "dbserver";
my $dsn = "DBI:mysql" . $host;
my $user = "chromatic";
my $pass = '';

my $dbh = DBI->connect($dsn, $user, $pass);

If this is inappropriate for your purposes, let me know. I am slightly confused by your question, and offer my apologies if I have misunderstood.
