I wouldn't do it that way. If your just using packages (and not OO), then look into DBI's connect_cached (hopefully your DBD supports it) and let each package/sub make it's own connection. Otherwise, I would pass the dbh to the constructors (and/or methods). 

  Hue::Foo::do_something( dbh => $dbh, data => $data );

update: Oops ... forgot to say this is an area where an OO approach would work best. 

package Hue::SQL;
sub new {
  return dbi->connect blah blah;
}

package Hue::Foo {
sub new {
  my $class = shift;
  my %args  = @_;

  my $self = {};
  bless $self, $class;

  $self->{dbh} = $args{dbh};
  $self;
}

sub do_something {
    my $self = shift;
    my %args = @_;
  
    $self->{dbh}->do( "sql query using $args{data}" );
}

package main;

use strict;
use warnings;

use Hue::SQL;
use Hue::Foo;

my $dbh = Hue::SQL->new();
my $foo = Hue::Foo->new( dbh => $dbh );
$foo->do_something( data => $data );
