This works for me in Perl

Also see 

http://www.imagemagick.org/Usage/formats/#gif_trans

#!/usr/bin/perl -w
use strict;
use Image::Magick;

my $image = Image::Magick->new;
my $rc = $image->Read("powerlogo.gif");
warn $rc if $rc;
 
$image->Transparent('color' => 'black');
$image->Write("output.png");
__END__
